Can a bishop eat a rook?

Excuse me, but I couldn't help but notice the phrase 'Can a bishop eat a rook?' floating around. Could you clarify, is this a metaphorical expression used in some context that I'm unaware of, or is it referring to a literal scenario involving chess pieces? I'm particularly intrigued by the juxtaposition of religious and game-related elements here. Is there a deeper meaning behind this question, or is it simply a playful wordplay? I'd be grateful for any insights you can provide.
