I didn't really think you were looking for information. You are correct that these doctrines were authored by man, as was the canon.
However to your point, and to the subject of this thread, Orthodox Anglicanism is based on the three legs of scripture, tradition and reason, and not one without the other two.
Yet, the bible explicitly warns against this sort of thing. Consider
But in vain do they worship me, teaching for doctrine the commandments of man. - Matthew 15:2-9, Colos 2:22 and Mark 7:7-13
There are contentions among you - That every one of you saith I am of Paul; and I of Apolos; and I am of Cephas; and I am of Christ, is Christ divided? was Paul crucified for you? or were you baptized in the name of Paul? - 1 Corinthians 1:11-13 & 3-5
The point I am trying to make is that a great deal of this is 'manufactured', having nothing to do with the Bible, nor of the teachings of Christ. When man takes upon himself the burden of 'manufacturing' tradition and reason; Apostasy is a very real and dangerous consequence.
I intentionally left out the really harsh verses that address this topic; as they would certainly be taken as a personal affront. It is not my intention to insult or denigrate; but to understand this approach. When one deviates from scripture, and institutes a new practice - this appears to be analogous to the game of Post Office we all played as children. The end result can be vastly different from the original message; and these are dangerous waters.
