Rav Moshe Shternbuch: Why Doesn't the Sandak Become Rich?
The Rema (YD 265:11) says that being a Sandak by a Bris is like being Makriv Kitores. Just like we know that bringing Kitores in the Bais HaMikdah makes you rich so too does being Sandak. If so why don't we see today that when a person is Sandak he becomes rich?
Rav Moshe Shternbuch (4:224) says that there are a few things a Sandak must do to be called a real Sandak that we don't do today. He brings Rebbi Akiva Eiger who says that a Sandak means holding the baby also during the Brachos and drinking the wine, not only just holding the baby during the cutting. Rav Shternbuch says that some say the Sandak must make the Brachos as well.
Additionally, says Rav Shternbuch, the Sandak is called the Ba'al Bris, meaning he pays for the Seudah as well as the Mohel if the Mohel is paid. He also quotes Rav Yaakov Kaminetzky who says that the Sandak pays for the Seudah. Others go further and say that the Sandak must buy the clothing or at least give a nice gift to the baby in order to be a true Baal Bris and Sandak.
Rav Shternbuch ends with one last point. He says that the Sandak should ask the father of the child to be Motzi him with the bracha of L'Hachniso B'Briso since the Sandak is also considered a Baal Bris. If you cover all your bases and do all this, says Rav Shternbuch, you will see wonders from the promise of Chazal!
