The Anathemas of the Second Council of Constantinople, No. 9

If anyone says that Christ ought to be worshipped in his two natures, in the sense that he introduces two adorations, the one peculiar to God the Word and the other peculiar to the man; or if anyone by destroying the flesh, or by confusing the Godhead and the humanity, or by contriving one nature or essence of those which were united and so worships Christ, and does not with one adoration worship God the Word incarnate with his own flesh, as the Church of God has received from the beginning; let him be anathema.
