Applying I Corinthians to today's ecclesia

"Now this I say, that everyone of you saith, I am of Paul [insert a well-known/respected brother]; and I of Apollos [insert a well-known/respected brother]; and I of Cephas [insert a well-known/respected brother]; and I of Christ. Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?" I Corinthians 1:12-13

"The flesh/mortal people should not cause divisions. The ecclesia is supposed to remove false teachers and if there are true teachers then they speak Christ's words, not their own. A brother can only be with Christ or against him, for he cannot be divided. The ecclesia is either permitting false teachers or causing strife in vain."
