"For whoever is not against us is for us."
—Jesus, Mark 9-40 (NWT)
The Jehovah’s Witnesses assert exclusivity. That is, they are the only true Christian faith. The JWs are not alone with this assertion amongst dominations that call themselves Christians. At most, only one such assertion can be true. However, rather than discussing grounds for this doctrine being true in regard to the JWs or any other denomination, I’d rather question the validity of such a doctrine on the part of any denomination in light of Jesus’ admonition as stated above.
The context is that the apostles tried to stop a preacher casting out demons in the name of Jesus notwithstanding the fact that he was apparently not affiliated with Jesus and his disciples. Jesus elaborates in verse 41:
“And whoever gives you a cup of water to drink because you belong to Christ; I tell you truly, he will by no means lose his reward.”
At the very least, Jesus seems to indicate that salvation is possible outside his religious organization. It is one’s actions and belief in him and his messianic mission on behalf of Jehovah rather than membership in his organization per se which is critical. In that light, why do JWs not only maintain exclusivity but discourage (if not strictly forbid) close associations (friendships, for example) with non-JWs?
Thank you.
