Christians took an offering that was not obligatory

The tried men of our elders preside over us, obtaining that honor not by purchase, but by established character. There is no buying and selling of any sort in the things of God. Though we have our treasure-chest, it is not made up of purchase-money, as of a religion that has its price. On the monthly day, if he likes, each puts in a small donation; but only if it be his pleasure, and only if he be able: for there is no compulsion; all is voluntary. These gifts are, as it were, piety’s deposit fund.  For they are not taken thence and spent on feasts, and drinking-bouts, and eating-houses, but to support and bury poor people, to supply the wants of boys and girls destitute of means and parents, and of old persons confined now to the house; such, too, as have suffered shipwreck; and if there happen to be any in the mines, or banished to the islands, or shut up in the prisons, for nothing but their fidelity to the cause of God’s Church, they become the nurslings of their confession. But it is mainly the deeds of a love so noble that lead many to put a brand upon us.

Chapter XXXIX

Christ will raise and judge the same body that died

Mock as you like, but get the demons if you can to join you in your mocking; let them deny that Christ is coming to judge every human soul which has existed from the world’s beginning, clothing it again with the body it laid aside at death;

Tertullian

Chapter XXIII

Spirits possess omnipresence

Every spirit is possessed of wings. This is a common property of both angels and demons. So they are everywhere in a single moment; the whole world is as one place to them; all that is done over the whole extent of it, it is as easy for them to know as to report. Their swiftness of motion is taken for divinity, because their nature is unknown. Thus they would have themselves thought sometimes the authors of the things which they announce; and sometimes, no doubt, the bad things are their doing, never the good.

Tertullian
Apology
Chapter XXII

Deity was Christ’s essential possession

Surely Christ, then, had a right to reveal Deity, which was in fact His own essential possession, not with the object of bringing boors and savages by the dread of multitudinous gods, whose favour must be won into some civilization, as was the case with Numa; but as one who aimed to enlighten men already civilized, and under illusions from their very culture, that they might come to the knowledge of the truth. Search, then, and see if that divinity of Christ be true. If it be of such a nature that the acceptance of it transforms a man, and makes him truly good, there is implied in that the duty of renouncing what is opposed to it as false; especially and on every ground that which, hiding itself under the names and images of dead, the labors to convince men of its divinity by certain signs, and miracles, and oracles.

Chapter XXI

Jesus is the primordial first-begotten Word of God, and one and the same with God

As, then, under the force of their pre-judgment, they had convinced themselves from His lowly guise that Christ was no more than man, it followed from that, as a necessary consequence, that they should hold Him a magician from the powers which He displayed,—expelling devils from men by a word, restoring vision to the blind, cleansing the leprous, reinvigorating the paralytic, summoning the dead to life again, making the very elements of nature obey Him, stilling the storms and walking on the sea; proving that He was the Logos of God, that primordial first-begotten Word, accompanied by power and reason, and based on Spirit,—that He who was now doing all things by His word, and He who had done that of old, were one and the same.

Jesus second coming will be all the majesty of Deity unveiled

The Jews, too, were well aware that Christ was coming, as those to whom the prophets spake. Nay, even now His advent is expected by them; nor is there any other contention between them and us, than that they believe the advent has not yet occurred. For two comings of Christ having been revealed to us:  a first, which has been fulfilled in the lowliness of a human lot; a second, which impends over the world, now near its close, in all the majesty of Deity unveiled; and, by misunderstanding the first, they have concluded that the second—which, as matter of more manifest prediction, they set their hopes on—is the only one.

Tertullian
Apology
Chapter XXI

Jesus is generated by the Father as God from God

We have been taught that He proceeds forth from God, and in that procession He is generated; so that He is the Son of God, and is called God from unity of substance with God.  For God, too, is a Spirit. Even when the ray is shot from the sun, it is still part of the parent mass; the sun will still be in the ray, because it is a ray of the sun—there is no division of substance, but merely an extension.  Thus Christ is Spirit of Spirit, and God of God, as light of light is kindled. The material matrix remains entire and unimpaired, though you derive from it any number of shoots possessed of its qualities; so, too, that which has come forth out of God is at once God and the Son of God, and the two are one. In this way also, as He is Spirit of Spirit and God of God, He is made a second in manner of existence—in position, not in nature; and He did not withdraw from the original source, but went forth.  This ray of God, then, as it was always foretold in ancient times, descending into a certain virgin, and made flesh in her womb, is in His birth God and man united.

Traditions of the Septuagint

Now in ancient times the people we call Jews bare the name of Hebrews, and so both their writings and their speech were Hebrew. But that the understanding of their books might not be wanting, this also the Jews supplied to Ptolemy; for they gave him seventy-two interpreters—men whom the philosopher Menedemus, the well-known asserter of a Providence, regarded with respect as sharing in his views.
