Does the Bible promote freedom to believe what we want?

1COR 1:10-13

I urge you, brothers, in the name of our Lord Jesus Christ, that all of you agree in what you say, and that there be no divisions among you, but that you be united in the same mind and in the same purpose. For it has been reported to me about you, my brothers, by Chloe’s people, that there are rivalries among you. I mean that each of you is saying, “I belong to* Paul,” or “I belong to Apollos,” or “I belong to Cephas,” or “I belong to Christ.” Is Christ divided? Was Paul crucified for you? Or were you baptized in the name of Paul?

Ignatius of Antioch

Chapter 4. Some wickedly act independently of the bishop

It is fitting, then, not only to be called Christians, but to be so in reality: as some indeed give one the title of bishop, but do all things without him. Now such persons seem to me to be not possessed of a good conscience, seeing they are not stedfastly gathered together according to the commandment.
