What does the notion of “offence against God” mean? … If I sin, something that God wanted and loved will eternally not be. This, by my own initiative. I am thus the cause – negating cause – of a privation in regards to God, a privation as regards the term or the effect that he wanted (not as regards the good of God himself)… Sin not only deprives the universe of a good thing, it deprives God himself of something wanted conditionally, but really, by him… Moral fault reaches the Uncreated, not in himself, since he is absolutely invulnerable in that regard, but in things, in the effects that he wants and loves. There, we can say that God is the most vulnerable of beings. We don’t need poison darts, cannons, or machine guns; all that is needed is an invisible movement in the heart of a free agent to wound God, deprive his antecedent will of something that he wanted and loved here-below from all eternity – and which will never be.
Jacques Maritain (1882–1973)
