Raise your hands, gentle readers, if you are familiar with this old saying: "There will always be prayer in public schools, as long as teachers keep giving math tests (or pop quizzes, etc.).

Actually, I don't know about you, but I did most of my public-school praying before Latin exams, and I was not praying in Latin. But I digress.

I shared that old saying simply to note that it only makes sense if the word "prayer" is defined as students sitting silently at their public-school desks praying for help. I would imagine that teachers would frown on a Catholic student getting out her rosary and reciting a Holy Mystery or two out loud. Ditto for students in a religious tradition that asks them to humble themselves with a few deep bows or prostrations. Burn some incense or light a few beeswax candles? I don't think so.

So what, precisely, does it mean to ask if it is acceptable to Muslims to pray in a Catholic church? I ask that question because of an interesting Religion New Service piece that ran the other day, with this headline: "Italian bishop tells priests not to let Muslims pray in churches." Here is the overture:

ROME (RNS) -- An Italian bishop has clashed with a pair of priests who want to invite Muslims to pray inside their churches in a bid to promote tolerance in a diocese in Tuscany.

“The deserved, necessary and respectful welcome of people who practice other faiths and religions does not mean offering them space for prayers inside churches designed for liturgy and the gathering of Christian communities,” Bishop Fausto Tardelli of Pistoia said in a statement. ... They can very well find other spaces and places,” Tardelli said.

The bishop was responding to pledges by two local priests, the Rev. Massimo Biancalani and the Rev. Alessandro Carmignani, to welcome 18 Muslim refugees by giving them space to pray inside their churches.

Note the emphasis on giving the Muslims "space to pray."

This raises all kinds of questions. Religion-beat pros, how many can you think of?
