Congress does not and cannot call only Christian invocations before every session: "The first rabbi...delivered an invocation in 1860 wearing a tallit and a yarmulke. He included the priestly blessing in his text. He was invited again although the Episcopal Church viewed his participation as an insult to Christianity. A Muslim imam was first given the honor in 1991 and a Hindu priest in 2000. Rabbis were invited to open a House of Representatives session seven times during the 112th Congress. "
