What do you mean “do we seclude ourselves or are we truly open to the thoughts and ideas of other people”? First, I don’t think Catholics seclude themselves and I don’t understand how anyone could say that we do. (Unless they misunderstand something Catholic–such as only Catholics receiving the Eucharist.) And I don’t think Catholics should be “truly open to the thoughts and ideas of other people” if by that you mean be open to being like Protestants. Catholicism, unlike other Christian denominations, is not, never has been, and never will be a democracy. Thank God for that!
