By Janet Meyer, Catholic Stand - Shortly after the shooting at a church in Sutherland Springs, Texas, a friend on Facebook posted a concern. She asked, in light of this kind of violence, how are we supposed to welcome strangers in our parishes?... I understand her fear. While worshiping this weekend in a downtown parish in a major city, I heard police sirens at least twice. They were very close. I wondered if they were on the same block as the church. The first time it happened, I looked around, assessing how to escape if necessary.
