The Body And Blood Of Jesus

The Father's "home is in inaccessible light" (1 Timothy 6:16), and "No one has ever seen God" (John 1:18).

Because God is Spirit, he can be seen only in the Spirit; for "it is the spirit that gives life, the flesh has nothing to offer" (John 6:63).

Likewise, neither is the Son, in that he is equal to the Father, seen by anyone but the Father and the Holy Spirit. Therefore, all who saw the Lord Jesus Christ and did not believe, in the Spirit, that he was divine, the true Son of God, were condemned. And so, too, now, all who see the sacrament of the Body of Christ, which is consecrated by the words of the Lord upon the altar in the hands of the priest in the form of bread and wine, and do not see and do not believe, in the Spirit, that it is divine, indeed, the Most Holy Body and Blood of our Lord Jesus Christ, are condemned, because the Most High himself gives witness and says, "This is my body, and the blood of the covenant" (Mark 14:22,24).
