So then we have both a reason and a time for the resurrection: a reason because nature in all its produce remains consistent with itself, and does not fail in the generation of men alone; a time because all things are produced at the end of the year. For the seasons of the world consist of one year. What wonder if the year be one since the day is one. For on one day the Lord hired the labourers to work in the vineyard, when He said, “Why stand ye here all the day idle?”

The causes of the beginnings of all things are seeds. And the Apostle of the Gentiles has said that the human body is a seed. And so in succession after sowing there is the substance needful for the resurrection. But even if there were no substance and no cause, who could think it difficult for God to create man anew whence He will and as He wills. Who commanded the world to come into being out of no matter and no substance? Look at the heaven, behold the earth. Whence are the fires of the stars? Whence the orb and rays of the sun? Whence the globe of the moon? Whence the mountain heights, the hard rocks, the woody groves? Whence are the air diffused around, and the waters, whether enclosed or poured abroad? But if God made all these things out of nothing (for “He spake and they were made, He commanded and they were created”), why should we wonder that which has been should be brought to life again, since we see produced that which had not been?

It is a cause for wonder that though they do not believe in the resurrection, yet in their kindly care they make provision that the human race should not perish, and so say that souls pass and migrate into other bodies that the world may not pass away. But let them say which is the most difficult, for souls to migrate, or to return; come back to that which is their own, or seek for fresh dwelling places. — Two Books on the Decease of His Brother Saytrus – Book II, para. 63-65.
