When the Torah forbids a marriage, it is never because one party is not good enough for the other. It is because the parties are not matched to each other. They are simply not soulmates. In the case of the Kohen and the convert, their soul dynamics clash, their spiritual energies contradict, and so they can't marry.
Well one could point out that all Bnei Yisrael became converts at Har Sinai which means, not only was Aharon HaKohen married to a convert but he himself was one too.
ReplyDeleteOut of curiousity, how do we handle Yecheskel's statement that a Kohen can married the divorcee of another Kohen?
