The contentions are clear since Paul spelled them out...And then comparing scripture with scripture, the conversation unfolds...
1Co_1:12 Now this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ.
1Co 3:4 For while one saith, I am of Paul; and another, I am of Apollos; are ye not carnal?
The contentions were over who had the most authority...Who was the holiest...
And Paul says, 'stick with the scriptures'...If one was over the other, or higher in rank than another, God would have told you in the scriptures...Do not go above what is written in the scriptures...Whether it be Peter, Paul or Mary...Pretty simple stuff there...And Paul say when you do this, it is carnal...
That verse so condemns Catholicism, which follows Cephas (Peter).
Peter is our first pope. You guys follow Luther. Nyah, nyah,....
