Actually, downtown there is one church which offers Eucharistic Adoration daily. There is a homeless shelter nearby, which closes during the daytime. A few of the longer-term people from that shelter make their way over to the church during the daytime, attend Mass, and stay during Adoration. A couple of them, probably who are either Catholic themselves or have had some teaching in the matter, are pretty much self-appointed “security” for Exposition: If someone disruptive enters the church, they either try to calm the person down, or in some cases escort them out. I’ve never seen any of the homeless “regulars” there act disrespectfully during Adoration–they usually either sit or kneel, same as the rest of us. Once in a blue moon someone goes into a confessional to sleep, but they certainly aren’t bothering anyone in there, and I’ve never heard of anything inappropriate going on in there. And if they can get out of the weather during our frigid Northeastern winters, that’s a corporal work of mercy for the parish as well as a spiritual work of mercy.
