Recently I seem to have been answering the same question multiple times on Quora.com, to wit: about Love Spells. The question is normally along the lines of Is placing a love spell on an ex morally wrong for a Christian?, or even Why are love spells considered white magic?
To answer the latter first: they are not. The term “love spell” is a euphemism. Historically, so-called “love spells,” as featured in classic grimoires of magick, are actually very nasty curses in which the caster wishes death / pain / unbearable torment / etc on the “loved one” (read: victim) unless they do exactly what the caster wants: e.g. fall in love with him, have sex with him, leave the safety of her parents’ house and run away with him, refrain from cheating or straying, etc.
Hence “love spells” ought really to be called “Rape Spells,” or “Sexual Harassment Spells,” or “Jealous Revenge Spells.” Not only would it be morally wrong for a Christian, it would be morally wrong for just about everyone.
