You can’t judge a denomination on the basis of the stands of politicians who happen to be members. Even if 98% of the members of a denomination support positions incompatible with Christianity, and even if church leaders are too nervous to take any action against straying members, that does not affect the orthodoxy of that denomination. Sadly, most Christians today take their moral and doctrinal formation from the Media, essentially a non-Christian religion in itself. That is not a reflection of denominations.
If the Church itself bends its teaching to fit the Media, as many have, then it is no longer orthodox. Evangelicals tend to equate “the Church” with “all the Christians” or “all the Christians in this city”. Catholics refer to “the Church” as also having an identity in itself, a guidance by what I call an invisible hand, in the Magisterium. Thus, “the Church” is always holy, even if, in a given year, every single Catholic including the pope are all scoundrels. The same is true with doctrine, even we don’t live up to it at the moment. We always come back, eventually. The Magisterium provides a fixed point, there will always be a place we can return to.
Forgive this interlude, hope to learn more from this thread on Lutheranism, and Northern Europe.
