All true Christians must maintain a clear distinction between themselves and Babylon the Great. Before learning the truth, a Bible student may have been a member of a false religion. He may have attended its religious services and shared in its activities. Or he may have contributed money to such an organization. Before a Bible student can be approved as an unbaptized publisher, he must break all ties with false religion. He should submit a letter of resignation or otherwise completely sever his membership in his former church and in any other organization that has ties to Babylon the Great. A true Christian must make sure that his secular employment has nothing to do with Babylon the Great. (2 Cor. 6:14-17) Why do we take such a firm stand? Because we do not want to share in the works and sins of religious organizations that are unclean in God’s eyes.​—Isa. 52:11. w19.10 12 ¶16-17
