Liberal Catholics are not necessarily dissidents at all. In fact, many "Liberals are really very conservative, wanting to get the Church back to its ORIGINAL practices, and stop all of the stuff that was added on between the 8th and 15th centuries.
If nothing changed in the church, and its liturgies, we would not have church buildings at all, we would meet for Mass at each others homes. Priests would not be full-time clergy, they would have a “day job” and be Priests (or Bishops) in addition to whatever they did in order to support their families.
There would be no “temples” at all (meaning huge, and hugely expensive churches), the Church would essentially be a home based religion.
Virtually ALL clergy would be married, just as Jesus himself chose only married men to be his apostles.
Clergy would be just another member of the community, not regarded as some kind of a “demi-God”, who has to be kowtowed to and treated as something ultra special. They would have one voice in the running of the local church, but only one voice and that voice would carry no more weight than any other, except in matters of direct faith and morals…
So, what you might consider to be very liberal positions, are, in actuality, very CONSERVATIVE positions.
There is absolutely no reason on earth why ANYONE, regardless of being either liberal or conservative, should be even thought of as someone to leave the church. Who are you, or anyone else, to sit in judgment of others?
