You are right liturgies change, canons change but Gods standards ,like God Himself , do not change. Heaven and earth will change but not Gods word. If Gods word is our benchmark then when liturgies and canons change they change either to the better ,meaning they are becoming more in line with Gods word ,or for the worse where they depart from the standard set in Gods word. The marriage canon changes for the worse.

First of all it should be done in a way that does not violate scripture. The church seem to give more credibility to the musings of the world then it does to scripture. I seem basic doctrine has been hammered out pretty well through the last 2000 years. Now a days people take issue with something because it may rub them the wrong way People want to get rid of the creed and in its place say the Shema in its place ,which is not a declaration of faith but a general statement about God. They do this because they have a problem with the deity of Christ ,the virgin birth, and the bodily resurrection of Jesus,again they want to violate scripture so that is more inline with their perspective, conforming it to their viewpoint. Scripture has the final word on all things pertaining to the faith we are to conforn to it not it to us.

Perhaps, Tony, you could constructively suggest how we might change our process for considering doctrine (assuming you accept there has to be such consideration from time to time).

Your “layman’s terms” seem nothing at all like a description of the process in place and being followed.
