Tertullian

For in the Gospel of Matthew he says, “Whosoever shall put away his wife, saving for the cause of fornication, causes her to commit adultery.” He also is deemed equally guilty of adultery who marries a woman put away by her husband. The Creator, however, except on account of adultery, does not put asunder that which he himself joined together, the same Moses in another passage enacting that he who had married after violence to a damsel should thenceforth not have it in his power to put away his wife. Now if a compulsory marriage contracted after violence shall be permanent, how much rather shall a voluntary one, the result of an agreement! This has the sanction of the prophet: “You shall not forsake the wife of your youth.” Thus you have Christ following spontaneously the tracks of the Creator everywhere, both in permitting divorce and in forbidding it. You find him also protecting marriage, in whatever direction you try to escape. He prohibits divorce when he will have the marriage inviolable; he permits divorce when the marriage is spotted with unfaithfulness. You should blush when you refuse to unite those whom even your Christ has united, and repeat the blush when you disunite them without the good reason why your Christ would have them separated.

I fully expect these heretics to seize upon the example of Elijah as reincarnated in John the Baptist, and thus they would have become our Lord espousing the doctrine of reincarnation. “Elijah indeed has come, and they knew him not.” And again, “And if you are willing to receive it, here is Elijah who was to come.” Was the question of the Jews to John, “Are you Elijah?” to be understood in a Pythagorean sense and not in reference to the divine pronouncement: “Behold, I send you Elijah, the Tishbite”? But their theory of transmigration refers to the recall of a soul that had died long before and to its insertion in some other body. Elijah, however, is to return not after leaving this life by death, not to be returned to his body, since he never left it, but he will come back to the world from which he has been removed. He will return not to take up a life he had left off but for the fulfillment of a prophecy. He will come back as Elijah, with the same name. How, then, could John be Elijah? The voice of the angel tells us: “And he shall go before the people in the spirit and power of Elijah,” not in the soul or body of Elijah. These substances are the specific property of each man, while “spirit and power” are extrinsic gifts conferred by the grace of God, and so they may be transferred to another according to the will of God as happened long ago with respect to the spirit of Moses.

We must after all this turn our attention to those scriptures also which forbid our belief in such a resurrection as is held by your Animalists (for I will not call them Spiritualists), that it is either to be assumed as taking place now, as soon as men come to the knowledge of the truth, or else that it is accomplished immediately after their departure from this life... Who has yet beheld Jesus descending from heaven in like manner as the apostles saw Him ascend, according to the appointment of the two angels? [Acts 1:11] Up to the present moment they have not, tribe by tribe, smitten their breasts, looking on Him whom they pierced. [John 19:37; Zechariah 12:10] No one has as yet fallen in with Elias; [Malachi 4:5] no one has as yet escaped from Antichrist; [1 John 4:3] no one has as yet had to bewail the downfall of Babylon. [Revelation 18:2] And is there now anybody who has risen again, except the heretic? He, of course, has already quitted the grave of his own corpse — although he is even now liable to fevers and ulcers; he, too, has already trodden down his enemies — although he has even now to struggle with the powers of the world. And as a matter of course, he is already a king — although he even now owes to Cæsar the things which are Cæsar's. [Matthew 22:21]
