On the Mysteries
Ambros of Milan
58. Wherefore, too, the Church, beholding so great grace, exhorts her sons and her friends to come together to the sacraments, saying: Eat, my friends, and drink and be inebriated, my brother. Song of Songs 5:1 What we eat and what we drink the Holy Spirit has elsewhere made plain by the prophet, saying, Taste and see that the Lord is good, blessed is the man that hopes in Him. In that sacrament is Christ, because it is the Body of Christ, it is therefore not bodily food but spiritual. Whence the Apostle says of its type: Our fathers ate spiritual food and drank spiritual drink, 1 Corinthians 10:3 for the Body of God is a spiritual body; the Body of Christ is the Body of the Divine Spirit, for the Spirit is Christ, as we read: The Spirit before our face is Christ the Lord. Lamentations 4:20 And in the Epistle of Peter we read: Christ died for us. 1 Peter 2:21 Lastly, that food strengthens our heart, and that drink makes glad the heart of man, as the prophet has recorded.
