ng witchcraft constantly or advocating for it or doing any form of “black magic” like cursing people, etc. A lot of purported witches will not use witchcraft for an evil purpose like a curse, because they believe whatever bad they do will come back on them.
I’d probably have a difficult time being very intimate friends with anyone who was a serious, practicing witch on a regular basis, even if they weren’t doing curses and such, as I think it would be an occasion of sin for me personally to be around that.
I have also known people who became friends or relationship partners with purported witches who were into black magic or serious occult stuff and did not have a good experience. Some of them were truly terrified by the time they got away from the person. These are not super-religious people either, they’re just ordinary people who didn’t realize what they were getting into or didn’t take someone’s heavy witchcraft involvement seriously.
If your friend is still a Catholic then you might remind them that witchcraft and the occult are against Church teachings and also dangerous because they open portals to demonic forces that the witch can’t control. If they continue to practice witchcraft then maybe you want to distance yourself from them so you don’t get sucked into anything.
