After much controversy and struggle in the Church, the Council of Chalcedon (451 AD) put out a formal definition on person of Christ, regarding his full divinity, humanity, and the union of the two natures. While not exhausting the depth and beauty of the person of Christ, it lays down important boundaries within which theologians must stay if they are to properly teach the glory of the Son who took on flesh for our salvation.
Chalcedon has stood as the bulwark of orthodox-catholic Christology across traditions for a millenia and a half, and yet, while lengthy expositions of it are available, it still takes some time digging to find a good, clean summary explanation of what the Definition actually says. That’s why I was pleased to find this passage in Calvin’s comments on John 1:14, “and the Speech* (Word) became flesh, and dwelt among us”, in which he briefly and clearly expounds the scriptural truth that Chalcedon teaches:
The plain meaning therefore is, that the Speech begotten by God before all ages, and who always dwelt with the Father, was made man. On this article there are two things chiefly to be observed. The first is, that two natures were so united in one Person in Christ, that one and the same Christ is true God and true man. The second is, that the unity of person does not hinder the two natures from remaining distinct, so that his Divinity retains all that is peculiar to itself, and his humanity holds separately whatever belongs to it. And, therefore as Satan has made a variety of foolish attempts to overturn sound doctrine by heretics, he has always brought forward one or another of these two errors; either that he was the Son of God and the Son of man in so confused a manner, that neither his Divinity remained entire, nor did he wear the true nature of man; or that he was clothed with flesh, so as to be as it were double, and to have two separate persons. Thus Nestorius expressly acknowledged both natures, but imagined two Christs, one who was God, and another who was man. Eutyches, on the other hand, while he acknowledged that the one Christ is the Son of God and the Son of man, left him neither of the two natures, but imagined that they were mingled together. And in the present day, Servetus and the Anabaptists invent a Christ who is confusedly compounded of two natures, as if he were a Divine man. In words, indeed, he acknowledges that Christ is God; but if you admit his raving imaginations, the Divinity is at one time changed into human nature, and at another time, the nature of man is swallowed up by the Divinity.
The Evangelist says what is well adapted to refute both of these blasphemies. When he tells us that the Speech was made flesh, we clearly infer from this the unity of his Person; for it is impossible that he who is now a man could be any other than he who was always the true God, since it is said that God was made man. On the other hand, since he distinctly gives to the man Christ the name of the Speech, it follows that Christ, when he became man, did not cease to be what he formerly was, and that no change took place in that eternal essence of God which was clothed with flesh. In short, the Son of God began to be man in such a manner that he still continues to be that eternal Speech who had no beginning of time.
The whole section is worth review as Calvin deftly comments on controversies both ancient and contemporary to his own day. Indeed, as challenges and confusions about just who Jesus is continue into our own, students and disciples of the Word would benefit from listening into the disputes of another age. While they’re framed in different ways, they are often-times structurally similar such that hearing the answer discussed in a context less immediate and personally-charged for us, can cast a clearer light for our own days.
Of course, the point of all this is not mere doctrinal correctness, but the life of doxology that follows. Christ is not properly worshipped and glorified, unless his magnificent person is properly taught and displayed according to Scripture.
Soli Deo Gloria
