I would suggest that what my post suggests is not Prisca theologia (thanks for the info - I'd not heard of it and have now learned some about it) is rather that all religion is actually bunk. Certainly (virtually?) all religions have a central core doctrine that is similar, but I don't believe that that necessarily points to a truth that they all have. Rather it points to a central human impulse of a huge creator-figure who will protect, right all wrongs and, in the end, show that *I* am correct. I suggest that while convenient and reassuring, there is no need to actually believe such a being exists.Everything you said is true. What all this ^^^^^ suggests is Prisca theologia. Look it up on Wikipedia.
Prisca theologia ("ancient theology") is the doctrine that asserts that a single, true theology exists, which threads through all religions, and which was anciently given by God to man.
Christianity, like other religions, e.g., Judaism, and Greek religions, borrowed ideas (i.e., underlying truths) from other religions (e.g., Biblical Noah’s flood from Chaldean Epic of Gilgamesh) and rewrote them into a new scriptural narrative. The people who originally understood the underlying truths and wrote them were a minority. The later people who literalize the myths and claim their religion is unique and that everyone else is going to hell are the misled. There happens to be more of them than the former group so they do a lot of harm to the underlying truth.
IOW, the few in every generation who perceive the better meaning of scripture are the ones whom God is revealing himself. All this other bickering and arguing whose religion is better is from those who don’t know what any of it actually meant to those who wrote it. It is why I spend so much time reading the best from each religion because everything else is just noise.
Go read Plutarch, “Isis and Osiris”, who as a priest for Apollo in the first century expounds on the Greek/Egyptian meaning of the myths and complains about the rabble who literalize the Myths. The point is that this ^^^^^^ has been going on since humans began writing scripture. The trick is to tune out the noise and cling to the good.
”Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things. What you have learned and received and heard and seen in me—practice these things, and the God of peace will be with you.” (Phillippians 4:8)
