Fragment IV.

For, in the view of apostles and prophets and teachers, the mystery of the divine incarnation has been distinguished as having two points of contemplation natural to it, ¹ distinct in all things, inasmuch as on the one hand it is the subsistence of perfect deity, and on the other is demonstrative of full humanity. As long, therefore, ² as the Word is acknowledged to be in substance one, of one energy, there shall never in any way be known a movement ³ in the two. For while God, who is essentially ever-existent, became by His infinite power, according to His will, sinless man, He is what He was, in all wherein God is known; and what He became, He is in all wherein man is known and can be recognised. In both aspects of Himself He never falls out of Himself, ⁴ in His divine activities and in His human alike, preserving in both relations His own essentially unchangeable perfection.
