"Creed" is the key to what is orthodox and what is not orthodox.

There can be best assumptions, however, there can also be room for error and misinterpretation.
Just my two cents.
I like what William Warburton supposedly said: "Orthodoxy is my doxy. Heterodoxy is another man's doxy." [He was presumably thinking of the word as used in the sense of a mistress, lover, or prostitute.]
