Over and over and over this "pagan day of the Sun" claim is made, disproved, and then reposted as if nothing happened. The other name for that is LYING.
However.....a cursory examination of the doctrines of the Catholic Church will find that most are wrong, most are invented, most are non scriptural and all are devised to keep the masses ignorant.
But an intelligent, thoughtful, prayerful examination will demonstrate otherwise. Next time try doing better than cursory.
Oh....? I must have missed that. Could you enlighten me on the evidence for disproving? I will need scripture, of course....and not the insane rambling of confused clerics.
While you're at it....tell everyone why the Greek in [Matthew 28:1][Mark 16:2][Luke 24:1][and John 20:1] does not say "PROTOS TES HEMERA HEBDOMADOS". That, of course is the Greek for "first day of the week" and appears no where in scripture! Not even anything similar!
You're silly little doctrine is an invention of foolish little men claiming to be infallible.... and their theology is a fraud!
