Me:”perhaps the less successful the church is, the more likely a Noahide movement could spread among non-Jews and lead them on a the true path.”
On the other hand, maybe the more religious the world becomes, the more open to Noahidism (or Judaism) people will be. Also, in the meantime (before the spread of Noahidism and the coming of Moshiach), Xians’ belief and trust in G-d and prayer and cultivation of brotherly love and humility (all important Jewish values) will probably be of much benefit to the individuals involved, despite their theological errors. So I guess a religious Jew could reasonably wish the Catholics well in reinvigorating and spreading their faith (among secular non-Jews.) I’m not sure what my own view is…
