Once upon a time, a padre suggested there were no atheists on foxholes ...
When I attended funerals of Second World War veterans from my Regiment, I quickly discovered the old guys could recite Psalms from memory ... not because they were particularly religious, but because they‘d had to do it so many times during the War ...
So, even though I‘m not that religious, I remember my padre‘s words.
And, amusingly enough, we were reminded of the field expedience of carrying a pocket bible (you know - the infamous one that "stops the bullet") ... just in case there was ever the requirement to hold a charge parade in the field (chuckle).
And, one last word - if you‘re dead, and you weren‘t terribly religious, then you probably won‘t worry or care too much about your funeral. However, if your family or parents were more religious than you, they might appreciate giving you an "appropriate" farewell (in this case, appropriate refers to them, not so much as you). For the sake of being gracious/altruistic, it doesn‘t hurt to put down your family‘s religion - it gives you manoeuver room later on ...
Here endeth the sermon (chuckle - no disrespect to my brothers who wear the collar - I just thought they‘d enjoy a chuckle hearing me, of all people, extoll the virtues of faith ... wink)
