The denominations are necessary to save us from the dictation of priests.

The Catholic Answers

The authority of the priesthood will be the subject of our consideration in due time. Meantime the denominations were not necessary according to the mind of Christ. He prayed that all might be one, as He and His Father are one. St. Paul said that even though an Angel from heaven were to preach a gospel differing from that already given, he should be regarded as accursed. No one had any right to establish the denominations, with their varying doctrines.
