> Catholic church left pagans to their own devices?
It varied, although generally the Catholic church was fairly open at integrating or even occasionally tolerating pagan practices or providing alternative options to people used to more polytheistic religions. Like the whole saint worshipping (“venerating”) thing. Often (with some exceptions) pagans found conversion fairly easy since they could just map their gods to equivalent Christian saints continue worshipping them. Basically every converted pagan society had a multi-generationa transition period.
Then you had stuff lime praying to magical corpses or body parts, so their previous owners could perform miracles. With some exceptions it has generally been a highly flexible religion before the reformation.
Islam is much more rigid about following the rules and stuff like idol worship (as a consequence they brought back visual arts back to the stone ages..)
