Yes you did actually:
Fortunately as the study of history, ancient texts and civilisations is becoming more and more secular and expert, and less the exclusive province of “theologians” and enthusiastic amateurs the prejudice is certainly less apparent and the findings more and more accurate.
Right there you are asserting that the “accuracy” is a function of the degree to which the study is “secular”.
I see from your plethora of posts on other topics you seem to have the same problems comprehending plain language. Is there a reason for this? Medical or?
See above.
