What was it that Fr. Kimel was talking about? Did it have something to do with those outside of Catholicism having no authority to accurately represent it? Could the same be said for Orthodoxy?
I'm thinking not so much of authority as of linguistic competence. Understanding any religious community requires, I think, the attainment of a real measure of fluency in the language, as well as a deep acquaintance with the culture of the community. The grammar of faith needs to be internalized precisely so that the words can be understood as the speakers of the language intend. It's never just a matter of reading words from the pages of a book, as one might do in a first year Spanish class.
This is not a correction directed at you Father Kimel since I know you are aware, but it is a definition offered to indicate that your use of "authority" was perfectly appropriate in this case. I realize that you are adjusting for a rather narrow usage here but I thought I'd offer this and suggest to those who are interested that they check out the PRIMARY meaning of authority to see that you were right in your lexical usage in the first place:
