His sacrifice, however, is complete.He is no longer on the cross but having provided the sacrifice said "It is Finished" and now sits at the right hand of the Father. Hebrews 10:10-12.
Then, in your estimation, Corinthians needs to be tossed???
Long after Christ publicly uttered the words "it is finished" from the cross I suppose Paul was wrong to "proclaim Christ crucified" (I Cor 1) and "know nothing while I was with you except Jesus Christ, and him crucified" (I Cor 2)?
