Saint Anselm,
Cur Deus Homo — Book First, Chapter XVIII
“ For who dares affirm that wickedness is more powerful to bind a man in servitude, after he has yielded to it at the first persuasion, than holiness to confirm him in liberty when he has adhered to it in the original trial? For as human nature, being included in the person of our first parents, was in them wholly won over to sin (with the single exception of that man whom God being able to create from a virgin was equally able to save from the sin of Adam) , so had they not sinned, human nature would have wholly conquered. ”
