To Florus 2.29

The case here concerns four persons: God the maker; the two parents, from whom the material is supplied to the maker; and the infant who is born. You say sin dwells in this company. I ask who commits it. God? You say no. The father? Again you say no. The mother? The same answer. The infant? No. And you still do not think it has been proved that something none of these four commits cannot exist among these four?
