I was just reading his
Admonitions today and he makes an analogy. Those who did not recognize the divinity of Jesus but could only recognize his flesh are similar to those who can only see the bread and wine and are blind to the divinity.
8All those who saw the Lord Jesus according to the humanity, therefore, and did not see and believe according to the Spirit and the Divinity that He is the true Son of God were condemned. 9Now in the same way, all who see the sacrament sanctified by the words of the Lord upon the altar at the hands of the priest in the form of bread and wine, and who do not see and believe according to the Spirit and the Divinity that it is truly the Body and Blood of our Lord Jesus Christ, are condemned. 10[This] is affirmed by the Most High Himself Who says, This is my Body and the Blood of my new covenant [which will be shed for many] (Mk 14:22, 24); 11and Whoever eats my flesh and drinks my blood has eternal life (Jn 6:55). 12It is the Spirit of the Lord, therefore, That lives in Its faithful, That receives the Body and Blood of the Lord. 13All others who do not share in this same Spirit and presume to receive Him eat and drink judgment on themselves (1Cor 11:29).
