I think you are way off target here. Murray was later accepted because after the death of Pious XII, liberals who shared many of Murray’s beliefs, took control of the Church. Many of these people, then Father Ratzinger among them, were being watched as possible sources of heresy. No, the Church has not changed one iota since then. What has happened is that it has been taken over by rebels. They naturally watch out for each other. Being orthodox and conservative is the surest way to end one’s clerical career nowadays. Gutierrez’ support for liberation theology can never be reconciled with Catholic dogma. There, at least, even the new generation of Church leadership is taking a firm stand. But perhaps that is only because Liberation Theology threatens the very existence of the Church and the status of office holders who have become quite comfortable. I would hope that resistance to it would be rooted in belief in dogma, but with so many office holders today questioning and reinterpreting dogma their own way, I have to wonder.

Making judgements simply by looking at the fruit doesn’t work when it comes to the Faith. We are to be guided by the dogmas, not by fads.
