Heresies past and present


I know I could probably do a word search but I would like to talk about what where the most common and first heresies on the forum that way if I have a question I can post it.

Any way what are some of the first heresies and what are the most important for a Catholic apologest to know?



For a while, This Rock was doing a series called “Heresy of the Month” where the writer would profile an ancient heresy and give its modern equivalent. If you click on “This Rock” at the top of the page and then search on “Heresy of the Month,” you should be able to find it.
