And so πηγὴ ξηρά. Serap. ii. 2. Orat. i. §14 fin. also ii. §2, where Athanasius speaks as if those who deny that Almighty God is Father, cannot really believe in Him as a Creator. If the divine substance be not fruitful (καρπογόνος), but barren, as they say, as a light which enlightens not, and a dry fountain, are they not ashamed to maintain that He possesses the creative energy?’ Vid. also πηγὴ θεότητος, Pseudo-Dion. Div. Nom. c. 2. πηγὴ ἐκ πηγῆς, of the Son, Epiphan. Ancor. 19. And Cyril, ‘If thou take from God His being Father, thou wilt deny the generative power (καρπογόνον) of the divine nature so that It no longer is perfect. This then is a token of its perfection, and the Son who went forth from Him apart from time, is a pledge (σφραγίς) to the Father that He is perfect.’ Thesaur. p. 37.
