The Council of Ephesus (431 AD)

Whosoever shall not confess that the flesh of the Lord giveth life and that it pertains to the Word of God the Father as his very own, but shall pretend that it belongs to another person who is united to him [i.e., the Word] only according to honour, and who has served as a dwelling for the divinity; and shall not rather confess, as we say, that that flesh giveth life because it is that of the Word who giveth life to all: let him be anathema.

If any one maintains that the flesh which is united with God the Word is by the power of its own nature life-giving, whereas the Lord himself says, “It is the Spirit that quickeneth; the flesh profiteth nothing”, let him be anathema. [He adds, “God is a Spirit”. If, then, any one maintains that God the Logos has in a carnal manner, in his substance, become flesh, and persists in this with reference to the Lord Christ; who himself after his resurrection said to his disciples, “Handle me and see; for a spirit hath not flesh and bones, as ye behold me having”; let him be anathema.]

The part enclosed in brackets is certainly a spurious addition and is wanting in many manuscripts. Cf. Marius Mercator [ed. Migne], p. 919.
