"'holy men who were taught by the Holy Spirit'" that's who the Church fathers are!
Please see my other response to nostr:npub1e5sergtz9hym5dj5ze4zfl8akll9lugnsdvhrmnt9yv9u0vuefhqxeylem . But the TL;DR: is that we received the Word of God from "holy men who were taught by the Holy Spirit" (see 2 Peter 1:16-21). Men did not bestow or grant authority; men only receptively recognized as genuine the authority already inherent in the Very Word of God--the authority of its Author, who has supreme authority in himself.

No, that verse in 2 Peter is referring to the authors/penmen of Scripture -- and the OT, specifically. The quote, "holy men who were taught by the Holy Spirit" is from (an older version of) the children's [First Catechism](https://opc.org/cce/FirstCatechism.html) and is meant to be a paraphrase of that verse in 2 Peter.
