Watchtower refuses to translate stauros as cross despite having no evidence to refute the long-standing ancient belief that Jesus died on a cross; and in spite of evidence that the Romans were in fact using crosses in executions by Jesus' day. They shun the word simply because of the use of crosses in ancient pagan religions.
Watchtower refuses to refer to their places of worship with the word church because of the word's supposed pagan origin or past usage to refer to pagan places of worship.
Now contrast Watchtower's self-righteous attitude of avoiding the use of all words having pagan religious usages, with the New Testament verse of 2 Peter 2:4:
Certainly God did not refrain from punishing the angels who sinned, but threw them into Tarʹta·rus, putting them in chains of dense darkness to be reserved for judgment.
Tartarus is a word that had rich pagan mythological meaning when it was written in the NT. The holy, righteous, inspired NT writer chose to use a word that has pagan religious meaning to refer to where God imprisoned the rebellious angels. But wait, there is more. The pagan meaning and usage of Tartarus - an underworld prison of darkness for rebellious gods - also harmonizes perfectly with it's usage in 2 Peter 2:4 in such a manner as to give credence to the pagan myth! Watchtower tries desperately and very transparently, to deny this very obvious and inconvenient fact, when explaining the use of word in this verse.
Doesn't it seem rather strange that the holy and righteous, pagan-shunning (as Watchtower would have us believe), Christian NT writer would choose such a false-religious word in such a manner as to give credence to a pagan myth?
Doesn't it seem rather strange and very revealing that the inspired bible writers are doing exactly what JWs today self-righteously shun as mixing pure worship with false worship?
This bible text exposes the utter self-righteousness of Jehovah's Witnesses in their shunning of the use of words like church and cross.
But it doesn't end there. We also have multiple uses of the pagan word hades which was regarded as the afterlife underworld of the dead where they continued living after death. So the word hades used in the NT has deep associations with the pagan notion of immortality of the soul and an automatic afterlife in the spirit realm. And yet, quite unlike JWs today, the writers of the NT had no puritanical hang-ups about using that word in their writings. Thus the NT reveals the utter self-righteousness of JWs in the way they stigmatize words based on past pagan usage - in a way that the inspired bible writers never did.
And there is more yet! The belief that Jesus was miraculously conceived of a virgin is not prophesied anywhere in the OT. But several pagan myths pre-dating christianity speak of demigods being born of a virgin. Yes, this idea that Jesus was born of a virgin is likely a pagan concept borrowed from other religions of the day.
I think these are good points to mention to JWs when they start with their self-righteous spiel about avoiding pagan influences in teaching and worship and to help them to see that the NT itself - and therefore Christianity - is polluted with pagan influences.
