It's convenient technique to say whatever we decide is the right decision and if we change our mind that is the right decision as well. There are many groups who use this same argument on me before including the Eastern Orthodox-as flawed as it is.
Am I'm to assume the RCC is correct or the Eastern Orthodox is correct? Both can be traced to the early church fathers. Both claim their church is infallible. Who's infallibility is correct?
Whichever one happens to have you tied to a stake, ready to light the bonfire under your heretical feet, of course. ;)
