# The cup of blessing Paul is speaking of God's blessing like the cup used in the Lord's Supper, which represents the blood and body of Christ. # that we bless "for which we thank God" # is it not a sharing in the blood of Christ? "we share in the blood of Christ.". Paul is reminding the Corinthians that the cup of wine we share symbolically represents us sharing in the blood of Christ. # The bread that we break, is it not a sharing in the body of Christ? "We share in the body of Christ when we share bread." # a sharing in "taking part in" or "equally participating with others in"
