[BluffTHIS!]

I would like to note before Peter chimes in again, that although over time doctrine has more fully developed, it does not change its core meaning. But liturgical practices and the methods of approach to the world do change. And you can't just claim those things also fall under the mantle of doctrine in order to stop those liturgical changes at the point you would desire. And if you really want to turn back the liturgical clock, then the western rite should simply adopt the liturgy of the catholic Maronite Rite since that is probably the closest to the way the apostles worshipped.
