Tatian, who maintaining the imaginary flesh of Christ, pronounces all sexual connection impure, who was also the very violent heresiarch of the Encratites, employs an argument of this sort: “If any one sows to the flesh, of the flesh he shall reap corruption;” but he sows to the flesh who is joined to a woman; therefore he who takes a wife and sows in the flesh, of the flesh he shall reap corruption.— Hieron.: Com. in Ep. ad Gal.
