Yes, just as we choose which traditions to honor - what day to worship on, which days to hold sacred (Paul talked about some of this, see below).

I think my point is different than yours concerning Paul's letter here. He certainly explains his doctrine, but he doesn't say, in effect "therefore whatever doctrine you explain is right also." Paul is speaking for the Church, not as one individual for himself only.

Another example is the Council of Jerusalem. Here they argue out doctrine, but they do not say: Ok, Peter you can have your own church and that doctrine, and James will have this one and that doctrine.

I.e., there is one doctrine and the Church has authority over what that doctrine and belief is.

Thanks very much for your reply.
