Yes, but what about those who don’t know God is the question. The Pope is methodically evangelizing non-believers with baby steps, with terms they can accept. Like recognizing good and evil, and recognizing the conscience of man, and whether they answer or ignore their conscience.
God “CAN” reach out to sinners and atheists without our supervision. Not all mankind is privy to the printed word. But, look what happened to Paul. Some require lightening to strike, but some can be drawn, even in the absence of a book and by reason, which many Christians often lack.
