There are no atheists in foxholes.
From the anthology Last Letters From Stalingrad, first published in 1950.
As one young soldier wrote:
"In Stalingrad, to put the question of God’s existence means to deny it. I must tell you this, Father, and I feel doubly sorry for it. You have raised me, because I had no mother, and always kept God before my eyes and soul. And I regret my words doubly, because they will be my last… you are a pastor, Father… I have searched for God in every crater, in every destroyed house, on every corner, in every friend, in my fox hole, and in the sky. God did not show Himself, even though my heart cried for Him. The houses were destroyed… on earth there was hunger and murder, from the sky came bombs and fire, only God was not there. No, Father, there is no God.”
Or as another young soldier lamented:
“This will be my last letter… perhaps forever… the situation has become untenable. The Russians are within three kilometers… If there is a God… I don’t believe any longer that God can be good, for then he would not permit such injustice. I don’t believe in it anymore, for he would have enlightened the minds of those people who began this war… I don’t believe in God anymore, because he betrayed us. I don’t believe anymore.”
These letters are but two examples of a fact rarely talked about: sometimes soldiers actually lose their faith on the battlefield, rather than find it.
Put another way, if you need to put people in horrific conditions of imminent death to gain converts then perhaps your god isn't all he's cracked up to be.
Anyway Morty, never seen it, might give it a go now.
