“So we worship in a fortress. But the metaphor should never run away with us. This does not mean we should walk around in here like we were an armed garrison—open carry in worship would make a liturgical statement, one that we don’t want to make. That statement would be that we consider all the others here to be potential enemies, not brothers and sisters. We are in the sanctuary, not in an Old West saloon. Concealed carry is different, and no more a problem that having a church building with a sprinkler system installed in case of fire. We would not be dubious about open carry at church because we were afraid of guns—far from it. The problem is liturgical, not practical. This is a secure fortress, and so we never want to install our anxieties into the liturgy. Here we are foreshadowing the time when we hang the trumpet in the hall, and study war no more (Is. 2:2-6).”
