Most XJWs likely have Matthew 28:19,20 burned into their brains, if indeed they ahve brains left after years of boring meetings.
But, in case you have forgotten the text, it says:
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
Happiness, according to the WTS would be yours if you loving prreached the message to endless shuit doors and minds.
But, according to the Pope:
"Don't proselytise; respect others' beliefs."
See his 9th commandment.
Well, I think the Pope wins, dont you?
