Tenet 24 – Jehovah’s Witnesses are the only true religion. wit.irr.org
Without defining “religion” it is difficult to even discuss this claim made by Watchtower, however, I think it is safe to say that what Watchtower means by this claim is that JW’s is God’s chosen organization.*
THE BIBLE TEACHES
James described what God sees as “true religion.”
Pure and undefiled religion before our God and Father is this: to care for orphans and widows in their distress, and to keep oneself from being polluted by the world. James 1:27
Jehovah’s Witnesses and the Watchtower Bible and Tract Society do not put primary emphasis on caring for orphans and widows. I am not aware that they put any emphasis there. Their emphasis is on meetings and going door to door with Watchtower publications. This alone would rule out Watchtower’s claim that they are the only true religion.

* Similarly, Jehovah is using only one organization today to accomplish his will. To receive everlasting life in the earthly Paradise we must identify that organization and serve God as part of it.” – The Watchtower 1983, February 15, page 12
