Q. Dear Rov, I recently overheard a very Frum Mohel refusing to do a Brith Mila on Shabbos, when he was told that the father of the newborn is not Jewish. It made me very angry that he was neglecting to be friendly and mekarev a family that could be turned into proper Baalei Teshuva. Could what be said be correct? After all we follow the mother’s status in determining what the child is, and the baby is Kosher!

A. Indeed many Poskim maintain that the Bris can be done on Shabbos (Pischei Teshuva Y.D. 266: 14, quoting Tiferes Lemoshe). As mentioned to me by some expert Moalim, that is the common tradition these days.

However, Maharam Shik (E.H. 100 – Y.D. 249) rules that the Bris should be avoided during Shabbos, since some Poskim disagree and maintain that such a child does require conversion. Beis Yitzchok (E.H. 29: 11) agrees.Horav Kalman Ochs shlit’a maintains that  מדינא דגמרא one May NOT encourage the goy father to convert.

Horav Shlomo Miller’s Shlit’a opinion is that it should not be done on Shabbos, to stress and emphasize that the father should convert properly
