We have just read of a successful marriage between a BT and a FFB – Rivka and Yitzhak (note that the Torah mentions her name, not just Eshes Yirtzhak, but I digress). Both have something to contribute: his davening is apparently more successful, but she seems to be a better judge of childrens’ character.
Anyway, I hope nobody is in the habit of has vesholom saying “I am not a BT”. Everyone should be, as I already quoted The Gerer Rebbe.
