I played Prayer wit 2 other holy cards in my hand on the first turn. The battle display shows +2 to each resource. At the end of each turn, however, I only have 3 more of each resource than I started the turn with.
To my mind:
Prayer Cost -1 each.
Prayer Effect +2 each.
Proeduction + 3 each.
Net should be +4 to each resource. However, I have exactly 3 more of each than I started with.

I tested it and it works fine. Please send screenshot before and after you play prayer. That way I will have a better way to analyze this bug.

Was there a quick/swift-card in the mix?

No, I just started the game, played Prayer and then compared my resources with my opponent's resources.

Well, once the game is done, you can just post the replay number.

Starting resources for each player are not the same. Perhaps that is where your confusion lies?

EricHerboso is right. If your opponent was first to act, you received +1/+1/+1 resource bonus in addition to your starting stock.
