One of the most hideously liberal organizations that had its birth in the morass of post-Vatican II Christianity is the "Call to Action" movement. To the best of my knowledge the "Call to Action" crowd never accomplished much of anything other than to question any teaching that Catholics or, for that matter, most Christians hold dear.
Now many of them are aging and not particularly gracefully. Here's a closing liturgy from the Southern California chapter of "Call to Action" that I think pretty fairly summarizes the whole movement. Sadly, there are many Episcopalians who might witness this "liturgy" and decide that this should become normative for them.
The link follows. However, I wouldn't suggest watching this right after a meal.
Now, if that's not enough, here's a "Mass" celebrated by Roman Catholic womenpriests(yes, that's the name of the organization). This "Mass" was also celebrated at "Call to Action".
