The ex was easily.....directed (if that's the right word) down certain paths. Annihilus does not believe in directing people down these types of paths, but she caught onto it because of the various book stores and shops that he took her to...
Annihilus is not of one religion, but has studied plenty of them - the most prevalent being Buddhism, Santeria, Voodoo and other 'non-traditional' studies. She picked up on the Wicca section and it just kind of went from there.
Once divorced from Annihilus's 'wide path' of discovery, she hooked up with a Christian Plumber and it was all downhill (no disrespect to Christians intended) from there.
So, Annihilus didn't really drive her to Christianity, she arrived there of her own accord after watching the Passion (the Mel Gibson movie). I sh!t you not.
