There is, and has yet to be provided within the official ARMA series, a Bible within a player's owned objects.

Rational for this feature, some real life soldiers were saved by their pocket Bible, taking rounds and shrapnel destined for ending their lives (eg. WW1, WW2, ...), and did not because of the Bible providing additional impenetrable barrier.

Although I think this is perverted not having a Bible (and/or other religious books) and should be escalated as a major bug request, I'll be courteous (of others' religious choices and those desiring female objects instead of an all male world) and mark this only as a minor feature request.
