We are completing this weekend the "quadfecta" of Sunday Feasts: Ascension, Pentecost, Holy Trinity, and now Corpus Christi. Today, the Solemnity of the Body and Blood of Jesus Christ, we focus on the Eucharist. The crucial passage from John 6, which is our Gospel today, lays out the concept of the real presence. “Whoever eats my flesh and drinks my blood remains in me and I in him” (Jn 6:56). Saint Paul is fairly explicit as well: “The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ?” (1 Cor 10:16).
