Tellos Athenaios, that is a very reasonable take on it.

I always wondered about the wars where both sides worshiped the same God. Would that not seem rather... Pointless from the perspective of a believer?

"Us english have the favour of God with us, contrary to you bastard Italians believing in your God! Now let us pray we shoot you to bits. Sure we still have to aim and stuff, God is not that much in our favour we can't aim, he help those who help themselves (making him slightly redundant one might think), but you know, he still is. Favouring us that is."
