By “other people” I meant “people other than infants,” not “people other than Christians.”
Not only is that what I meant, it’s what I said.
But we're still back to the original problem, that is, defining the Body of Christ as "people who have a right to attend church services" and kept apart from "people who are a disruption". Is being socially disruptive an excommunicable sin in your parish? Does the Catholic Church instruct the priest to without communion from people who are a social disruption?
