For, as we must often be saying, he is one and the same, truly Son of God, and truly Son of Man. God, inasmuch as “all things were made by him, and without him nothing was made.” Man, inasmuch as he was “made of a woman, made under the law.” The nativity of the flesh is a manifestation of human nature; the Virgin’s child-bearing is an indication of Divine power. The infancy of the Babe is exhibited by the humiliation of swaddling clothes: the greatness of the Highest is declared by the voices of angels. He whom Herod impiously designs to slay is like humanity in its beginnings; but he whom the Magi rejoice to adore on their knees is Lord of all. — Council of Chalcedon (A.D. 451), Session II

Since, then, we have shown that all of us are by Scripture called children; and not only so, but that we who have followed Christ are figuratively called babes; and that the Father of all alone is perfect, for the Son is in Him, and the Father is in the Son; it is time for us in due course to say who our Instructor is.

He is called Jesus. Sometimes He calls Himself a shepherd, and says, “I am the good Shepherd.” (John 10:11) According to a metaphor drawn from shepherds, who lead the sheep, is hereby understood the Instructor, who leads the children—”the Shepherd who tends the babes. For the babes are simple, being figuratively described as sheep. “And they shall all,” it is said, “be one flock, and one shepherd.” (John 10:16) The Word, then, who leads the children to salvation, is appropriately called the Instructor (Pædagogue).

With the greatest clearness, accordingly, the Word has spoken respecting Himself by Hosea: “I am your Instructor.” Now piety is instruction, being the learning of the service of God, and training in the knowledge of the truth, and right guidance which leads to heaven. And the word “instruction” is employed variously. For there is the instruction of him who is led and learns, and that of him who leads and teaches; and there is, thirdly, the guidance itself; and fourthly, what is taught, as the commandments enjoined.

Now the instruction which is of God is the right direction of truth to the contemplation of God, and the exhibition of holy deeds in everlasting perseverance. — Book I, Chapter 7

These things, beloved, we write unto you, not merely to admonish you of your duty, but also to remind ourselves. For we are struggling on the same arena, and the same conflict is assigned to both of us. Wherefore let us give up vain and fruitless cares, and approach to the glorious and venerable rule of our holy calling. Let us attend to what is good, pleasing, and acceptable in the sight of Him who formed us. Let us look stedfastly to the blood of Christ, and see how precious that blood is to God, which, having been shed for our salvation, has set the grace of repentance before the whole world. Let us turn to every age that has passed, and learn that, from generation to generation, the Lord has granted a place of repentance to all such as would be converted unto Him. Noah preached repentance, and as many as listened to him were saved. Jonah proclaimed destruction to the Ninevites; but they, repenting of their sins, propitiated God by prayer, and obtained salvation, although they were aliens [to the covenant] of God. — Chapter VII

Hear. “Behold what manner of love the Father has given us, that we should be called sons of God, and be (1 John 3:1) (such).” For whoso are called sons, and are not sons, what profits them the name where the thing is not? How many are called physicians, who know not how to heal! how many are called watchers, who sleep all night long! So, many are called Christians, and yet in deeds are not found such; because they are not this which they are called, that is, in life, in manners, in faith, in hope, in charity. But what have ye heard here, brethren? “Behold, what manner of love the Father has bestowed upon us, that we should be called, and should be, the sons of God: therefore the world knows us not, because it has not known Him, us also the world knows not.” There is a whole world Christian, and a whole world ungodly; because throughout the whole world there are ungodly, and throughout the whole world there are godly: those know not these. — Homily IV

—And every tongue,— should —confess that Jesus Christ is Lord, to the glory of God the Father.— That is, that all should say so; and this is glory to the Father. Seest thou how wherever the Son is glorified, the Father is also glorified? Thus too when the Son is dishonored, the Father is dishonored also. If this be so with us, where the difference is great between fathers and sons, much more in respect of God, where there is no difference, doth honor and insult pass on to Him. If the world be subjected to the Son, this is glory to the Father. And so when we say that He is perfect, wanting nothing, and not inferior to the Father, this is glory to the Father, that he begat such a one. This is a great proof of His power also, and goodness, and wisdom, that He begat one no whit inferior, neither in wisdom nor in goodness. When I say that He is wise as the Father, and no whit inferior, this is a proof of the great wisdom of the Father; when I say that He is powerful as the Father, this is a proof of the Father’s power. When I say that He is good as the Father, this is the greatest evidence of His goodness, that He begat such (a Son), in no whit less or inferior to Himself. When I say that He begat Him not inferior in substance but equal, and not of another substance, in this I again wonder at God, His power, and goodness, and wisdom, that He hath manifested to us another, of Himself, such as Himself, except in His not being the Father. Thus whatsoever great things I say of the Son, pass on to the Father. Now if this small and light matter (for it is but a light thing to God’s glory that the world should worship Him) is to the glory of God, how much more so are all those other things?

Let us then believe to His glory, let us live to His glory, for one is no use without the other; when we glorify Him rightly, but live not rightly, then do we especially insult Him, because we are enrolled under Him as a Master and Teacher, and yet despise Him, and stand in no dread of that fearful judgment seat. It is no wonder that the heathen live impurely; this merits not such condemnation. But that Christians, who partake in such great mysteries, who enjoy so great glory, that they should live thus impurely, this is worst of all, and unbearable. For tell me; He was obedient to the uttermost, wherefore He received the honor which is on high. He became a servant, wherefore He is Lord of all, both of Angels, and of all other. — Homily VII.

Moreover, we learn from the Scripture itself, that God gave circumcision, not as the completer of righteousness, but as a sign, that the race of Abraham might continue recognizable. For it declares: “God said unto Abraham, Every male among you shall be circumcised; and you shall circumcise the flesh of your foreskins, as a token of the covenant between Me and you.” (Gen 17:9-11) This same does Ezekiel the prophet say with regard to the Sabbaths: “Also I gave them My Sabbaths, to be a sign between Me and them, that they might know that I am the Lord, that sanctify them.” (Ez 20:12) And in Exodus, God says to Moses: “And you shall observe My Sabbaths; for it shall be a sign between Me and you for your generations.” (Ex 21:13) These things, then, were given for a sign; but the signs were not unsymbolical, that is, neither unmeaning nor to no purpose, inasmuch as they were given by a wise Artist; but the circumcision after the flesh typified that after the Spirit. For “we,” says the apostle, “have been circumcised with the circumcision made without hands.” (Col 2:11) And the prophet declares, “Circumcise the hardness of your heart.” — Book IV, Chapter 16
