That does knock on the head Mardukm's repeated claim that Saint Gregory Palamas supported the IC:
"He Who is God by nature, the Co-unoriginate and Coeternal Word and Son of the Transcendent Father, becomes the Son of Man, the Son of the Ever-Virgin. "Jesus Christ the same yesterday and today, and forever" (Heb. 13:8.), immutable in His divinity and blameless in His humanity, He alone, as the Prophet Isaiah prophesied, "practiced no iniquity, nor deceit with His lips" (Is. 53: 9). He alone was not brought forth in iniquity, nor was He conceived in sin, in contrast to what the Prophet David says concerning himself and every other man (Ps. 50/51: 5).
