This modern idea that one can inherently divorce morality and ethics from religion and the accumulated wisdom of a society molded by it in some way, shape, or form (whichever religion that may be) is contemptible to me.
Morality and ethics are built from the accumulated wisdom of a culture group over time. That wisdom is sourced, undeniably from that group’s religious notions, even if the overt influence of said religion declines. The stories, the ideas, the oral sayings, written texts, songs and dances of religion, all of it will inform a community’s or civilization’s conception of personal right and wrong, as well as lay the groundwork for ethical norms. The use of reason, as advocated for by those who believe this idea, is the mere filter through which a people periodically evaluates their notions for the purpose of deciphering and preserving those permanent standards. It is not itself the foundation of ethics and morality.
This notion that one can separate the two unto itself is not only audaciously ignorant, but the attempt at formulating any set of moral and ethical standards without concern for even the foundational values built from *insert religion here* will result in a system that lacks authentic depth and meaning, one which rests upon nothing more than the considerations of passing whim (i.e. “I just want to do something. Right or wrong be condemned!”), or a mentality of imprudent individualism (i.e. “something is right or wrong merely because I as an individual say that it is.”), or some other transient thing.
