Having a piece of paper saying what the "official" policy means nothing if you have a bunch of bishops and sisters running around advocating their opposing views. Rome may set policy from the safety of Italy but they do little to hurd in their wayward flock. Does practice what they preach come to mind?
There are very few Protestant groups that allow these sort of things and those that do are finding their denominations dwindling. It would be beneficial to recongize these modernalistic dangers in all of our churches/Churches. This isn't isolate to a select group.
Again, the difference is doctrine vs. doctrine. Some Protestant groups allow all kind of perversions as a matter of doctrine. We don't. We also consider bearing a false witness a serious sin, by the way. You?
