Introduction

 

       The doctrine of the hypostatic union teaches that Jesus Christ is both undiminished deity and unfallen humanity combined together forever in one person.  The theanthropic person is one hundred percent God, and at the same time one hundred percent man.  Though the emphasis is usually on the union between the two natures, it is apparent from Scripture that there were times when Jesus spoke only from His humanity, such as when He was thirsty (John 19:28) or hungry (Matthew 4:2), or only from His deity, such as when He forgave sins (Mark 2:5-7) or referred to Himself as the great “I Am” (John 8:58), or from both natures simultaneously when speaking as the unique mediator between God and man (John 14:6; 1 Timothy 1:5). 

 

       The unified division that exists in the theanthropic nature of Jesus Christ is perplexing.  How can there be unity between two distinct natures?  How can Jesus be both all-knowing and not knowing, everywhere and at one particular place, all-powerful and helpless?  The purpose of this paper is to address some of the conflicts related to the hypostatic union, and specifically, issues related to divine and human knowledge.  Effort will be made to keep both natures of the hypostatic union undiminished and unconfused so that Jesus is not viewed as schizophrenic. 

 

 

The Hypostatic Union

 

The term Hypostatic is derived from hypostasis, which word, according to the Standard Dictionary, means “The mode of being by which any substantial existence is given to any independent and distinct individuality.” Thus it follows that a union of hypostasis is a union of natures that are within themselves independent and distinct. The expression Hypostatic Union is distinctly theological and is applicable only to Christ in whom, as in no other, two distinct and dissimilar natures are united.1

 

            The biune nature of Jesus Christ is a revealed mystery; that is, Scripture reveals that Jesus Christ is both God and man, yet this revelation leaves much that is unanswered and perplexing to the human mind.  The doctrine of the unfallen humanity and full deity of Jesus Christ was a hot topic during the first few centuries of the church, and did not get hammered out until the Council of Chalcedon in A.D. 451.

 

In Christology, the Council of Chalcedon (451) distinguished between the one hypostasis of Christ’s incarnate being and the two physeis, ‘natures’ (divine and human), which were united in what Alexandrian theologians called ‘the hypostatic union’.2

 

            The doctrine basically states that “the Lord Jesus Christ is one person with two natures indissolubly united, the one nature being that of the eternal Son of God, the other that of man, in all respects human.”3  Dr. Paul Enns helps develop this definition by stating:

 

The two natures of Christ are inseparably united without mixture or loss of separate identity. He remains forever the God-man, fully God and fully man, two distinct natures in one Person forever. Though Christ sometimes operated in the sphere of His humanity and in other cases in the sphere of His deity, in all cases what He did and what He was could be attributed to His one Person. Even though it is evident that there were two natures in Christ, He is never considered a dual personality. In summarizing the hypostatic union, three facts are noted: (1) Christ has two distinct natures: humanity and deity; (2) there is no mixture or intermingling of the two natures; (3) although He has two natures, Christ is one Person.4

 

            This precise definition is important so that as one begins to address complications and difficulties with the union, he may have an anchor from which to remain safely attached to the shores of biblical truth.  The diagram below is a rough visualization reflecting the Chalcedonian definition.

            The above diagram attempts to keep unity within the circle, and also attempts to point out the two distinct natures.  The figure attempts to incorporate the truth that Jesus Christ is “full deity and perfect humanity united without mixture, change, division, or separation in one Person forever.”5 

 

 

God the Son

 

When Christ came, a Person came, not just a nature; He took on an additional nature, a human nature—He did not simply dwell in a human person. The result of the union of the two natures is the theanthropic Person (the God-man).6

           

            God the Son is considered the second member of the Trinity, and is co-equal (He shares the same attributes), co-infinite (He is not bound by time or space), and co-eternal (He eternally exists) with the other members of the Godhead.  As God, Jesus Christ has the same attributes as the other members of the Trinity.  It appears to this writer that there are ten major attributes of God found in the Scripture, with minor attributes merely being subcategories.  The attributes are as follows:

 

1.      Omniscience (Psalms 139:1-6; Psalms 147:5; Jeremiah 16:17; Matthew 6:8; Matthew 6:31-33; Matthew 10:29, 30; Hebrews 4:13).

a.       Foreknowledge (Acts 2:23Romans 8:29; 11:2; 1 Peter 1:2).

2.      Omnipresence (Genesis 28:15; Jeremiah 23:24; Psalms 139:7-12; Hebrews 13:5).

3.      Omnipotence (Job 42:2; Jeremiah 27:5; Matthew 19:26; Like 1:37; Samuel 17:47; Psalms 27:1; Isaiah 26:3, 4; Isaiah 40:28, 29; Jeremiah 33:2, 3; II Corinthians 9:8; Ephesians 1:19; Ephesians 3:20; II Timothy 1:12).

4.      Righteousness (Psalms 11:7; Psalms 97:6; Psalms 111:3; Psalms 119:137; Jeremiah 23:6; Romans 10:3-4; I John 2:29;).

5.      Justice (Psalms 9:7, 8; Psalms 19:9; Psalms 50:6; Psalms 58:11; Hebrews 10:30, 31).

6.      Sovereignty (Deuteronomy 4:39; I Samuel 2:6-8; I Chronicles 29:11; II Chronicles 20:6; Isaiah 45:5-7; Daniel 4:35; Acts 17:24-25).

b.      Predestination (Acts 4:28; Romans 8:29-30; 1 Corinthians 2:7; Ephesians 1:5, 11).

7.      Immutability (Psalms 102:26, 27; Malachi 3:6; Ecclesiastes 3:14; Hebrews 13:8).

a.       Faithfulness (Lamentations 3:21-23; Numbers 23:19; I Kings 8:56; Hebrews 10:23).

8.      Veracity (II Samuel 7:28; John 17:17; John 14:6; John 14:16, 17; I John 5:20).

9.      Love (Jeremiah 31:3; I John 4:7-12; I John 4:16).

a.       Mercy (Romans 9:15-18; 11:30-32; Ephesians 2:4).

b.      Goodness (Matthew 19:17; Mark 10:17; Luke 18:18-19).7

10.  Eternal Life (Deuteronomy 33:27; Job 36:26; Psalms 9:7; Psalms 90:2; Psalms 102:27; Lamentations 5:19; I Timothy 1:17).8

 

            The New Testament declares that Jesus Christ is fully God, and that he should be recognized as such.  In fact, “hundreds of explicit verses call Jesus “God” and “Lord” and use a number of other titles of deity to refer to him, and in many passages attribute actions or words to him that could only be true of God himself.”9  Two of the strongest references to the deity of Christ are found in Titus 2:13 and 2 peter 1:1 where the use of the Granville Sharp Rule affirms that Jesus Christ is both God and Savior.10  Dr. Wayne Grudem helps to clarify this point by stating:

 

Although the word theos, “God,” is usually reserved in the New testament for God the Father, nonetheless, there are several passages where it is also used to refer to Jesus Christ.  In all these passages the word “God” is used in the strong sense to refer to the one who is the Creator of heaven and earth, the ruler of all.  These passages include John 1:1; 1:18 (in older and better manuscripts); 20:28; Romans 9:5; Titus 2:13; Hebrews 1:8 (quoting Ps. 45:6); and 2 peter 1:1.11

 

            After careful study and analysis, a serious student of the Bible must conclude that the Bible clearly teaches that Jesus Christ is God; and more so, that He is God in the flesh (John 1:1, 14). 

 

 

Jesus the Man

 

            As unfallen man, Jesus was born as Adam was created.  Upon original creation Adam possessed a body, soul, and human spirit, but he lost his human spirit as a result of the fall (Genesis 2:16-17),12 and the human race was plunged into spiritual death (Genesis 5:3).  Since Jesus did not have a human father (Matthew 1:18), he was not subject to inheriting Adam’s Old Sin Nature and subsequent spiritual death (Romans 5:12).  Therefore, Jesus is unique (John 1:14, 18; Hebrews 11:17) in that he is born trichotomous and did not know spiritual death as the rest of humanity.  The figure below illustrates the constitutionality of Adam as he was first created, and also the constitutionality of Jesus from birth.13

            God supernaturally impregnated the Virgin Mary so that Jesus was fully human, and yet He was minus Adam’s Old Sin Nature (Romans 5:12; Hebrews 4:15).  Once the incarnation occurred at conception, it was destined to last forever. 

 

Though His deity is eternal, the humanity was gained in time.  Therefore, the theanthropic Person—destined to be such forever—began with the incarnation.14

 

            Naturally one might wonder about the Old Testament theophanies of Jesus Christ and consider how they are similar or different from the incarnation.  If a theophany is indeed an actual physical manifestation of God, would that not constitute an incarnation?  Dr. Charles Lee Feinberg addresses this issue quite well by stating:

 

It is true that the hypostatic union and the theophanies have one great feature in common: in both the one acting is the Second Person of the Godhead. However, there is only one hypostatic union whereas there have been several theophanies-that to Abraham, that to Lot, that to Moses, that to Joshua, and to others. The theophanies were vouchsafed to a very limited number of people; the hypostatic union, or rather the consequences of the union, was visible to many. But above all, the theophanies were temporary, while the union of the two natures in Christ is eternal.15

 

            So, it is noted that the difference between the hypostatic union and Old Testament theophanies is that the theophanies were many and temporary, whereas the incarnation of Jesus Christ happened once and will remain forever.  It should be noted that there are differing views regarding Jesus’ status in heaven as to what condition He remains in hypostatic union.  For example, John Calvin “taught that the two natures are united without any transfer of attributes. An attribute could not be taken away from a nature without changing the essence of that nature.”16  This statement may seem innocuous, until one considers Luther’s view of the current status of the hypostatic union:

 

The Lutheran view of the two natures teaches that attributes of the divine nature are extended to the human nature with some important results. One important doctrinal result is the ubiquity of the human body of Christ, that is, the omnipresence of the divine nature of Christ is transferred to the human body of Christ. Consequently, the human nature of Christ passed into a ubiquitous state at the ascension and is physically present in the elements of Holy Communion. Although the elements do not change, the person partakes of Christ who is “in, with, under and by” the bread and cup.17

 

            There does not appear to be any clear argument from Scripture that Jesus Christ has changed in any way since the inception of the hypostatic union.  After the resurrection Jesus ascended into heaven (Acts 1:9-11) where He was observed going up in bodily form.  Two angels spoke and said “this Jesus, who has been taken up from you into heaven, will come in just the same way as you have watched Him go into heaven.”18  It would seem sensible to believe that since Jesus went up in bodily form, and that He will return in bodily form, that He currently resides in heaven in that same bodily form.  Jesus still exists in true unfallen humanity. 

 

 

Problems related to the Hypostatic Union

 

The reality in which undiminished Deity and unfallen humanity united in one Theanthropic Person has no parallel in the universe. It need not be a matter of surprise if from the contemplation of such a Being problems arise which human competency cannot solve; nor should it be a matter of wonder that, since the Bible presents no systematized Christology but rather offers a simple narrative with its attending issues, that the momentous challenge to human thought and investigation which the Christ is, has been the major issue in theological controversy from the beginning to the present time.19

 

            The hypostatic union is a logical contradiction.  The Bible teaches that Jesus is 100% God and at the same time 100% man.  This formula does not fit into human reasoning.  One could consider the Greek pantheon in Classical mythological literature and understand how someone such as Zeus could copulate with Alcmene and produce the god-man Herakles, who was 50% god and 50% man; such reasoning is logical.  But the biblical formula regarding the Person of Christ is such that the Christian is asked to believe that 1+1=1.  Starting with human reason alone, one could never come to such a conclusion; but after understanding and accepting the biblical formula, one cannot reason it away either.  The believer must accept the fact that “Christ is ever represented as one Person, though He be the coalition of two so widely diverse qualities.”20  The hypostatic union “is difficult to comprehend because it posits the combination of two natures that by definition have contradictory attributes.”21

 

The Person of the Lord Jesus Christ is at one and the same time of vast intrinsic importance and of almost insurmountable difficulty of explanation. It defies and transcends any human intellectual effort to explain or analyze it. No successful attempt has ever been made to fathom the mystery of the hypostatic union. It is all the more inscrutable, because there is, and has been, no situation or pattern similar or analogous to it in the history of the world.22

 

            Of all the possible logical complications associated with the hypostatic union, the comparison of divine and human knowledge stands at the forefront.  Omniscience knows all there is to know, both actual and probable.  However, God does not know sin or death experientially, though through divine imagination He might know them theoretically.  If God knew sin personally, He would be a sinful God, and this is to be rejected.  God the Son does not know sin or Death; yet Jesus knows both sin (by judicial imputation), and death (separation from God the Father in time). 

 

In his human nature there was growth in knowledge, but this must not be construed as a contradiction of His divine omniscience. Limitations in knowledge as well as limitations in power are related to the human nature and not to the divine.23

 

            Sin and death are possible only to humans.  In His humanity Jesus experienced sin judicially on the cross as it was imputed to Him, though not personally as though He produced it Himself.  He (in His humanity) experienced death physically (cessation of human life) and spiritually (separation from God the Father in time).  In His deity, God the Son did not experience either sin, or death, since it is impossible for deity to either sin or die.  Therefore, in His humanity Jesus knows things that God the Son cannot know, for if He (God the Son) were to know them experientially, He would cease to be deity.  How does this affect the unity of the theanthropic person?

 

            In the hypostatic union there are things deity knows that humanity does not know, and likewise, there are things humanity knows that deity does not know.  So how does one reconcile a perfect union where incompatible knowledge exists?  If it is said that God the Son has knowledge as a result of the hypostatic union, was that knowledge new?  Did God the Son obtain new knowledge from the hypostatic union that He could not have known experientially prior to that event?  Perhaps, if one considers Old Testament theophanies as God temporarily taking human form for the purpose of interacting with His children.  Of course, one is left with the same question at the moment God took human form prior to the hypostatic union, for if the form was truly human, did God at that moment learn something experientially which had not been known before?  Is experiential knowledge different from theoretical knowledge?  Does God speculate as to what humans know, since it is possible for humans to know things He cannot (i.e. sin and death)?  Why would God create beings that have the ability to do things He Himself cannot do, and with whom He could never fully relate?

 

             If one says God the Son experientially knows sin and death after the crucifixion, then it must be declared that God changed with reference to what He knows.  If one says God the Son did not experientially know sin and death after the cross, then it must be concluded that a perpetual division exists in the hypostatic union.  That is, God the Son and the humanity of Jesus know different things.

 

            The gamut of theological speculation is infinite.  Sometimes the questions may help one to think critically; sometimes the questions may lead to heresy, especially if the one asking the questions seeks to force a reasonable explanation.  This is one of those cases where some knowledge is helpful in determining an orthodox theology, and too much information leads to a headache.

It is equally natural to suppose that the divine nature would be injured to some extent if combined with that which is human, and the human nature would be exalted out of its precise limitations if combined with the divine. The teaching of the Scriptures serves to save the reader from such natural conclusions. The Deity of Christ is unimpaired by its union in one Person with that which is unfallen human nature; and the unfallen humanity retains its normal limitations. The confusion and uncertainty that would follow if these natures were subject to problematical alterations is beyond estimation.27

 

            So what is one to do?  Faith and reason are not incompatible, as though the believer is forced to choose one over the other; for God Himself calls to us and says “Come now, and let us reason together” (Isaiah 1:18).  However, though reason can lead the believer to know certain things, this knowledge does not guarantee an infinite comprehension of the knowledge obtained.  For God also says:

 

8“For My thoughts are not your thoughts, nor are your ways My ways,” declares the LORD. 9“For as the heavens are higher than the earth, so are My ways higher than your ways and My thoughts than your thoughts. Isaiah 55:8-9

 

It is best to know that one can know the doctrine of the hypostatic union, and be content with what is presented in Scripture. 

 

 

Conclusion

 

Of these two natures it may be affirmed from the evidence which Scripture provides, that they are united in one Person, and not two; that in this union, that which is divine is in no way degraded by its amalgamation with that which is human; and, in the same manner and completeness, that which is human is in no way exalted or aggrandized above that which is unfallen humanity.28

 

            The doctrine of the hypostatic union is both marvelous and mysterious.  That Jesus is undiminished deity and perfect humanity united together forever in one person expresses the genius and love God.  From the creation of Adam, God knew He would someday take upon Himself a body for the purpose of redeeming fallen humanity.  The hypostatic union is a condescension of love, an expression of the greatness of God, and a mystery no man can ever fully comprehend. 

 

            Though there are infinite logical difficulties related to the hypostatic union, these should not deter one from accepting the truthfulness of the doctrine.  For though reason can help one to know the doctrine, it must always be kept in mind that reason alone (unaided by the Holy Spirit) is never the measure of truth.

10.     The Granville Sharp Rule states that when the copulative kaiv connects two nouns in the same case and the first noun is preceded by a definite article whereas the second noun is not, then both nouns refer to the same person.  Both Titus 2:13tou/ mega,lou qeou/ kai. swth/roj h`mw/n VIhsou/ Cristou/” (our great God and Savior, Jesus Christ), and 2 peter 1:1 “tou/ qeou/ h`mw/n kai. swth/roj VIhsou/ Cristou” (our God and Savior , Jesus Christ) make absolutely clear that the New Testament teaches that Jesus Christ is fully God.

12.     After the fall, all mankind is spiritually dead and classified as dichotomous, possessing only a human soul and body.  At the moment of regeneration (John 3:3-7) God the Holy Spirit creates a new human spirit ex nihilo and imputes it to the person who trusts in the finished work of Christ on his behalf; thus, the new Christian is trichotomous (1 Thessalonians 5:23; Hebrews 4:12) possessing a human body, soul, and spirit.

13.     This writer is aware of the arguments related to the constitutionality of man from the various theological frameworks and believes that Adam and Christ both entered the world trichotomous.  After consideration, this writer has decided not to go into the issues related to dichotomy and trichotomy due to the length of this paper.

24.     This comparison is not exhaustive, but rather representative of some of the distinctions that exist between the two natures of Jesus Christ. 

25.     In Philippians 2:7 the Greek verb kenovw refers to Jesus giving up the right to use some of His divine attributes while in hypostatic union on the earth; however, it does not mean that God the Son ceased to posses certain attributes.  Since there is no one greater than God, any limitations upon God must of necessity be self-imposed. 

26.     When Jesus died spiritually on the cross, it must not be compared to Adam’s spiritual death which resulted in the cessation of his human spirit; rather, Jesus spiritual death was judicial in that He was separated from God the Father during that time He was being judged for sin on the cross.  Since the imputation of human sin upon the humanity of Jesus was judicial, his spiritual death must be regarded as judicial as well.  Jesus did not cease to be trichotomous, even while He was undergoing the crucifixion.
