Seems pretty clear-cut to me. Governments shouldn't be promoting a particular religious sect. I thought this was decided by the Supreme Court decades ago.
LinkWhen the Town Council convenes in the tiny town of Brentwood in Prince George’s County, it is customary to open the session with the Lord’s Prayer. But two residents say that the prayer favors Christianity over other religions and thus violates the U.S. Constitution. Two residents, one a Catholic, the other a Buddhist, filed suit in U.S. District Court in Greenbelt on Tuesday challenging the town’s practice.
