I have been a Catholic for 48 years and have never seen any “un welcomes” to any faith at are Church.In fact are priest at St.Peters makes a statement “welcome to all visitors”.How does the parshioners know your Lutheran?.At our church we shake hands after the Lords Prayer and I don’t know what the persons relgious denomination is. In fact my wife who is a devout Catholic grow up with her dad a Lutheran and mother Catholic with no problems.
