If unity is so important, why are there so many different denominations? - Unity - TouchPoints

1 Corinthians 1:10-13I appeal to you, dear brothers and sisters, by the authority of our Lord Jesus Christ, to live in harmony with each other. Let there be no divisions in the church. Rather, be of one mind, united in thought and purpose. For some members of Chloe’s household have told me about your quarrels, my dear brothers and sisters. Some of you are saying, “I am a follower of Paul.” Others are saying, “I follow Apollos,” or “I follow Peter,” or “I follow only Christ.” Has Christ been divided into factions? Was I, Paul, crucified for you? Were any of you baptized in the name of Paul? Of course not!

Although Scripture discourages divisions among believers in Jesus, diversity can be positive if all are striving for a united purpose of serving and glorifying God.
