There is no human leader of the church...
Luk 22:26 But ye shall not be so: but he that is greatest among you, let him be as the younger; and he that is chief, as he that doth serve.
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 1:13 Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?
1Co 1:14 I thank God that I baptized none of you, but Crispus and Gaius;
1Co 1:15 Lest any should say that I had baptized in mine own name.
1Co 1:16 And I baptized also the household of Stephanas: besides, I know not whether I baptized any other.
1Co 1:17 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect.
One at a time.
The pope is called the servant of the servants of God. He serves the church not himself, all that he has for his use does not belong to him.
No one says they are of the pope. We are God’s children, brothers and sisters of Christ and it is Christ whom we worship and serve.
Christ’s church has certainly been divided, but not by us.
The rest is simply Paul explaining his call and gifts for the church, the body of Christ as well as his concern that certain of the faithful were aligning themselves with certain Apostles and not adhering to the one faith those Apostles preached. It does not mean anything else.
