Logical and Theological Reasoning
Jesus is God—His words have power to create reality. Just as He said, “Let there be light” and light existed, His declaration “This is my body” effects what it says.
Paul’s letters (1 Corinthians 10:16; 11:23–29) warn against receiving the Eucharist unworthily because it is a true participation in Christ’s body and blood—not a mere symbol.
