Once again, I will stress the point. "ask".
As a weapon of ceremony or trust is still, in effect, a weapon. I've worked with ministers that allowed "weapons" in the church and those who didn't. And it really has no bearing on whether or not that particular clergyman is "reasonable". Some clergyman are just more, let's say, adament about weapons inside the church. By the way, when I say church, I mean sanctuary. One of the ministers who didn't allow weapons in the sanctuary couldn't care less if you walked around the rest of the building with an M-16. I've also worked with another one that wouldn't allow sgian dubhs to be worn at the front of the church. One that wouldn't allow any weapons to be worn with blade pointed downwards so the kilted groomsmen laid them at their feet before the cermony. Other clergymen had them lay there sgian dubhs on a separate table. Others wouldn't have them anywhere near the inside of the sanctuary. And others didn't give a dang about the knifes. I'll also point out that they are from a plethora of denominations and perhaps that has something to do with it. I personally wouldn't care either way but I'm not clergy I just clean the place and lock the doors when the festivities are done.

Just a heads up,
