People can preach heresy without formal excommunication. The Catechism of the Catholic Church represents sound doctrine and what the Church teaches. Bishop Gumbleton does not teach what the Catechism teaches on homosexuality.

[Mr. Lucky]

Fair enough, but you're applying a different standard to the Roman Catholic church than to orthodox Protestant churches.

In your apparent view, screwballs who claim to be Protestant derogate the legitimacy of all Protestant churches, but Bishop Gumbleton doesn't diminish the legitimacy of the Roman Catholic church because he's wrong and therefore doesn't count.

still removing oneself from the submitting to the authority of the church is as good as self excommunication
