statement that the thing renounced was not divine essence, or anything belonging essentially to the divine nature. The Logos remained what He was in these respects when He became what He was not; equal to God in nature (ἴσος Θεῷ), while ceasing for a season to be His equal in state (ἴσα Θεῷ). As to the latter, the exchange of forms may, as Martensen and others hold, be compatible with the theory of a double life; not an absolute exchange, but one relative to the incarnate life of the Logos.
