"Contrarily, each member is the body, not just a part of the body, but the whole body. Therefore, each of you should say: "I'm not a part of the Body; I am the whole Body of Christ, I am the Church."
Some folks just should not do apologetics.
And I doubt you realize it but that is Scripture, God breathed by the Holy Spirit.
I just copied and pasted the whole chapter.
The body of Christ is NOT just one member or organ. The criticism of Protestantism and the number of denominations then carries no weight. The different churches can just be considered different parts of the one body with their different functions, all working together in the unity of the Spirit.
