Jesus humanity and divinity are evident from reading Paul

It is well for us that in another passage (the apostle) calls Christ “the image of the invisible God.” For will it not follow with equal force from that passage, that Christ is not truly God, because the apostle places Him in the image of God, if, (as Marcion contends,) He is not truly man because of His having taken on Him the form or image of a man? For in both cases the true substance will have to be excluded, if image (or “fashion”) and likeness and form shall be claimed for a phantom. But since he is truly God, as the Son of the Father, in His fashion and image, He has been already by the force of this conclusion determined to be truly man, as the Son of man, “found in the fashion” and image “of a man.”  For when he propounded Him as thus “found” in the manner of a man, he in fact affirmed Him to be most certainly human. For what is found, manifestly possesses existence. Therefore, as He was found to be God by His mighty power, so was He found to be man by reason of His flesh, because the apostle could not have pronounced Him to have “become obedient unto death,” if He had not been constituted of a mortal substance.

Christ is before all things — eternally begotten

He calls Christ “the image of the invisible God.” We in like manner say that the Father of Christ is invisible, for we know that it was the Son who was seen in ancient times (whenever any appearance was vouchsafed to men in the name of God) as the image of (the Father) Himself. He must not be regarded, however, as making any difference between a visible and an invisible God; because long before he wrote this we find a description of our God to this effect: “No man can see the Lord, and live.” If Christ is not “the first-begotten before every creature,” as that “Word of God by whom all things were made, and without whom nothing was made;” if “all things were” not “in Him created, whether in heaven or on earth, visible and invisible, whether they be thrones or dominions, or principalities, or powers;” if “all things were” not “created by Him and for Him” (for these truths Marcion ought not to allow concerning Him), then the apostle could not have so positively laid it down, that “He is before all.” For how is He before all, if He is not before all things? How, again, is He before all things, if He is not “the first-born of every creature”—if He is not the Word of the Creator? Now how will he be proved to have been before all things, who appeared after all things?  Who can tell whether he had a prior existence, when he has found no proof that he had any existence at all?

Christ is the one who said “Let there be light”

Now who was it that said; “Let there be light?” And who was it that said to Christ concerning giving light to the world: “I have set Thee as a light to the Gentiles”—to them, that is, “who sit in darkness and in the shadow of death?” (None else, surely, than He), to whom the Spirit in the Psalm answers, in His foresight of the future, saying, “The light of Thy countenance, O Lord, hath been displayed upon us.” Now the countenance (or person) of the Lord here is Christ. Wherefore the apostle said above: “Christ, who is the image of God.” Since Christ, then, is the person of the Creator, who said, “Let there be light,” it follows that Christ and the apostles, and the gospel, and the veil, and Moses—nay, the whole of the dispensations—belong to the God who is the Creator of this world, according to the testimony of the clause (above adverted to), and certainly not to him who never said, “Let there be light.”

The incarnation of God is the weakness of God though stronger than men

Now, what is that “foolishness of God which is wiser than men,” but the cross and death of Christ? What is that “weakness of God which is stronger than men,” but the nativity and incarnation of God?

Christ, as God, descended to Hades so that we won’t have to

Now although Christ is God, yet, being also man, “He died according to the Scriptures,” and “according to the same Scriptures was buried.” With the same law of His being He fully complied, by remaining in Hades in the form and condition of a dead man; nor did He ascend into the heights of heaven before descending into the lower parts of the earth, that He might there make the patriarchs and prophets partakers of Himself. (This being the case), you must suppose Hades to be a subterranean region, and keep at arm’s length those who are too proud to believe that the souls of the faithful deserve a place in the lower regions. These persons, who are “servants above their Lord, and disciples above their Master,” would no doubt spurn to receive the comfort of the resurrection, if they must expect it in Abraham’s bosom. But it was for this purpose, say they, that Christ descended into hell, that we might not ourselves have to descend thither.

Christ’s name is everywhere worshipped as God and Lord

But Christ’s Name is extending everywhere, believed everywhere, worshipped by all the above-enumerated nations, reigning everywhere, adored everywhere, conferred equally everywhere upon all. No king, with Him, finds greater favour, no barbarian lesser joy; no dignities or pedigrees enjoy distinctions of merit; to all He is equal, to all King, to all Judge, to all “God and Lord.” Nor would you hesitate to believe what we asseverate, since you see it taking place.

Chapter VII

Christ was no less the Logos in the womb, the cradle or the cross

Christ is the inner conception ‘in the bosom of His Father;’ and that is properly the Word. And yet the Word is the intention uttered forth, as well as conceived within; for Christ was no less the Word in the womb of the Virgin, or in the cradle of the manger, or on the altar of the cross, than he was in the beginning, ‘in the bosom of his Father.’ For as the intention departs not from the mind when the word is uttered, so Christ, proceeding from the Father by eternal generation, and after here by birth and incarnation, remains still in Him and with Him in essence; as the intention, which is conceived and born in the mind, remains still with it and in it, though the word be spoken. He is therefore rightly called the Word, both by His coming from, and yet remaining still in, the Father.

The Holy Spirit enables man to fulfill his calling as a creature of God

The Christian Church lives by the Holy Spirit. The Spirit alone is the guarantee of God’s Kingdom on earth. He is the sole guarantee that God’s life and truth and love are with men. Only by the Holy Spirit can man and the world fulfill that for which they were created by God. All of God’s actions toward man and the world—in creation, salvation and final glorification—are from the Father through the Son (Word) in the Holy Spirit; and all of man’s capabilities of response to God are in the same Spirit, through the same Son to the same Father.

The Nature of the Logos

The name Word bestowed upon the Son of God reveals better than any other name the mystery of the inner relationship between the First and Second Persons of the Holy Trinity, God the Father and God the Son. A thought and a word are distinct from each other in that the thought dwells in the mind, whereas the word is the expression of the thought; yet the two are inseparable. The thought does not exist without the word, nor does the word without the thought. A thought is like a word which is concealed within, and a word is that which gives expression to the thought. The thought takes the form of a word to convey the content of the thought to its hearers. Looked at in this way, the thought, being an independent principle, is the father of the word, and the word is the son of the thought. The word cannot exist prior to the thought, yet it does not originate from without; it comes from the thought and remains inseparable from the thought. Similarly, the Father, the supreme and all-encompassing Thought, produced from His bosom the Son, the Word, His first Interpreter and Herald.

Christ receives the prayers of the saints

For as much, then, as there is but one Son of man whose advent is placed between the two issues of catastrophe and promise, it must needs follow that to that one Son of man belong both the judgments upon the nations, and the prayers of the saints.
