“The larger context does not negate the fact that the body and blood of Jesus is mentioned right next to the need to “discern the body”. “
Paul’s argument is straight forward.
The Lord’s Supper reflects the Body & Blood of Christ. To fail to examine oneself includes examining how we treat other believers in the Body of Christ.
Paul corrects the for their failures to treat others in the Body of Christ the way they should. He does this before the sub-point of the Lord’s supper and he continues it after the sub-point of the Lord’s Supper.
Aha. That is better. So you understand now that the sub-point, as you call it, is the Eucharist and not the assembly of Christians in the Church? Except it is not really a "sub-point", -- it goes on for the better part of the chapter. Also, the words St. Paul uses: "discern the body of the Lord" which apparently can "condemn" one -- does not match your "reflect". Christ did not say "this bread reflects my body" did He?
