When we were children in school we learned about the mythical man/god hero figures of the Romans, the Babylonians, the
Egyptians, the Persians, the Greeks, the Norse, the Polynesians, and scores of other cultures around the world. They were taught to us as
myths and we understood them as myths. They were fictional stories created by people (usually by priests, shamans, medicine men, various
thaumaturges or other authority figures) whose primary objectives were to control the ignorant, restless masses.
However, the Christian authority figures from the earliest days of the religion insisted that their sacred myth, (both New Testament and Old Testament) conceived by self appointed and self authenticating religious zealots were factual history, and they were taught as such. Never mind that much of what was taught, e.g., ancient stories about virgin births, resurrection of dead bodies of mythical hero figures and other assertions that deny and defy the known laws of the universe are, and always have been, religious myths.
To accept the Judeo-Christian myth as factual history when all of the other myths are understood as cultural fictions is probably the most egregious intellectual error in the history of Western Civilization. The Renaissance, The Reformation and the Enlightenment have accomplished little in correcting this intellectual failing.
Some of the most accomplished biblical scholars, theologians and assorted ecclesiastics have understood this for centuries. The fiction, fraud, forgery and fantasy that characterizes every book in the Bible has been documented by some of the most able people in the history of Christianity. This is so well known by so many of the most competent former religious believers that to continue to perpetuate and promulgate this intellectual error is a crime against humanity.
Unfortunately, uncritical minds have always believed whatever is convenient and comfortable.
