Chazal liken Esav, the Romans and Christians to the pig= externally kosher but internally not. Rav Kook stands on the difference between Israel & Christianity, which did away with the observance of mitzvot, claiming that all God wants is morality, to looks nice but Crusade. The Romans legitimize physical pleasure even when it's selfish, the Catholics see physical pleasure as problematic, and especially the social, political, military & economic as void of God and belonging to "Caesar". They simplistically divide the world as black-white, good-bad, physical-spiritual, setting unrealistic goals which infer that God made mistakes in creating physical pleasure. Judaism believes God is Perfect and there is good phys. pleasure vs. the selfish.
