I often see people on CAF getting upset about what the heresies of modernism having infected the Church. Now without getting into whether or not female alter servers or the playing of guitars amount to heresy or involve the spirit of heresy, I often wonder if those same people so hyper-vigilant against modernism are as wary of the old heresies like Janenism and Catharism, not to mention Manicheanism, which strongly influenced the Cathars.
Indeed, I think that there is little worry that many posters on this forum might become infected by modernism, insofar as it really does exist in the contemporary Church, and yet such things seems to preoccupy the minds of many posters. But I can definitely see the spirit of these earlier heresies rearing their heads here, and yet none are wary. Though it does not, I think, usually lead to embracing these heresies, but rather, the life-hating nature of these heretical spirits may simply drive people to atheism. Indeed, I believe there was a poster here who once called for the whitewashing of the Sistine Chapel roof - and one day, as it seems from that poster’s history, the pressure of this way of thinking caught up with the poster and they wholly lost their faith.
