A millennial kingdom on Earth before reign in heaven

But we do confess that a kingdom is promised to us upon the earth, although before heaven, only in another state of existence; inasmuch as it will be after the resurrection for a thousand years in the divinely-built city of Jerusalem, “let down from heaven,” which the apostle also calls “our mother from above;” and, while declaring that our πολίτευμα , or citizenship, is in heaven, he predicates of it that it is really a city in heaven.

Christ is the catholic temple of God in which he is worshipped

In these very words Isaiah says: “And it shall come to pass in the last days, that the mountain of the Lord,” that is, God’s eminence, “and the house of God,” that is, Christ, the Catholic temple of God, in which God is worshipped, “shall be established upon the mountains,” over all the eminences of virtues and powers; “and all nations shall come unto it; and many people shall go and say, Come ye, and let us go up to the mountain of the Lord, and to the house of the God of Jacob; and He will teach us His way, and we will walk in it: for out of Sion shall go forth the law, and the word of the Lord from Jerusalem.”

God called his body bread

For so did God in your own gospel even reveal the sense, when He called His body bread; so that, for the time to come, you may understand that He has given to His body the figure of bread, whose body the prophet (Jeremiah) of old figuratively turned into bread, the Lord Himself designing to give by and by an interpretation of the mystery.

The Magi worshipped Christ as God

For the East generally regarded the magi as kings; and Damascus was anciently deemed to belong to Arabia, before it was transferred to Syrophœnicia on the division of the Syrias (by Rome). Its riches Christ then received, when He received the tokens thereof in the gold and spices; while the spoils of Samaria were the magi themselves. These having discovered Him and honored Him with their gifts, and on bended knee adored Him as their God and King, through the witness of the star which led their way and guided them, became the spoils of Samaria, that is to say, of idolatry, because, as it is easy enough to see, they believed in Christ.

God was born

Come then, wind up your cavils against the most sacred and reverend works of nature; inveigh against all that you are; destroy the origin of flesh and life; call the womb a sewer of the illustrious animal—in other words, the manufactory for the production of man; dilate on the impure and shameful tortures of parturition, and then on the filthy, troublesome, contemptible issues of the puerperal labour itself! But yet, after you have pulled all these things down to infamy, that you may affirm them to be unworthy of God, birth will not be worse for Him than death, infancy than the cross, punishment than nature, condemnation than the flesh. If Christ truly suffered all this, to be born was a less thing for Him. If Christ suffered evasively, as a phantom; evasively, too, might He have been born. Such are Marcion’s chief arguments by which he makes out another Christ; and I think that we show plainly enough that they are utterly irrelevant, when we teach how much more truly consistent with God is the reality rather than the falsehood of that condition in which He manifested His Christ. Since He was “the truth,” He was flesh; since He was flesh, He was born.

Chapter XI

The flesh became a vestment for God himself

But yet, if we look steadily into the subject, there is really no substance which is worthy of becoming a vestment for God. Whatsoever He is pleased to clothe Himself withal, He makes worthy of Himself—only without untruth. Therefore how comes it to pass that he should have thought the verity of the flesh, rather than its unreality, a disgrace?

Christ regenerated our lives through incarnation and resurrection

…none but Christ could become incarnate by being born of the flesh in order that by His own nativity He might regenerate our birth, and might further by His death also dissolve our death, by rising again in that flesh in which, that He might even die, He was born.

Tertullian

Chapter IX

Christ and the Spirit are one substance with the Creator

For when you do not deny that the Creator’s Son and Spirit and Substance is also His Christ, you must needs allow that those who have not acknowledged the Father have failed likewise to acknowledge the Son through the identity of their natural substance; for if in Its fulness It has baffled man’s understanding, much more has a portion of It, especially when partaking of the fulness.
