And sometimes Paul referred to the Eucharist as bread and sometimes the body of Christ. Do you find that comment by Paul out of line? Erroneous? Muddled?
Do you, like Mark, doubt that Jesus was a man?
1 CORINTHIANS 12:27 - "Now ye are the body of Christ, and members in particular." EPHESIANS 4:12 - "For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ." 1 CORINTHIANS 10:16 - "The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?"
To what is Paul referring when he uses the phrase, "body of Christ?" He's referring to believers, to His flock, to us.
The bread is not the body of Christ physically. The bread is the "communion of the body of Christ."
The Lord's Supper is a communion of members of His church where we remember His sacrifice and partake of His grace.
