[quote:1rdik2cv]Hmm…..not exactly sure if that is one. Although the church takes a while to define things, the substance of the doctrine in it’s entirety sure seems to be there with the Eucharist. You can read several early church fathers that saw the Eucharist as we see it now. I could be wrong, but I guess I don’t see much GROWTH in the Church when it comes to the Eucharist. It was mystery back then, it’s a mystery now.
How about the Papacy?[/quote:1rdik2cv]
Hmm… I think I know what you are getting at. I think the Trinity is definitely the best example of development of Doctrine, but I’m sure there are others.
