Oral instruction from such men is one thing. Doctrines fabricated by a bunch of "clerics" in some conclave are another thing entirely.

Please cite a doctrine from any conclave that is fabricated.

Well, I’m not sure exactly how or where the Catholic Church invented many of its doctrines, but they sure didn’t get them from the Apostles or from scripture. I’m thinking of things like purgatory, celibate clergy, transubstantiation, praying to saints, the cult of Mary, veneration of relics...just to name a few.
