Phillip and the Etheopian Eunich came to mind…
Then the angel of the Lord spoke to Philip, “Get up and head south on the road that goes down from Jerusalem to Gaza, the desert route.” So he got up and set out. Now there was an Ethiopian eunuch, a court official of the Candace, that is, the queen of the Ethiopians, in charge of her entire treasury, who had come to Jerusalem to worship, and was returning home. Seated in his chariot, he was reading the prophet Isaiah. The Spirit said to Philip, “Go and join up with that chariot.” Philip ran up and heard him reading Isaiah the prophet and said, “Do you understand what you are reading?” He replied, “How can I, unless someone instructs me?” So he invited Philip to get in and sit with him. … Then Philip opened his mouth and, beginning with this scripture passage, he proclaimed Jesus to him. (Acts8:26-31,35)
Note that the Etheopian was reading the prophetic work of Isaiah, did not understand it and wished to be instructed. Phillip was sent by God though an angel to instruct the Etheopian. I’m unusre if Philip in this passage was the Apostle or the deacon from Acts 6. What is clear is that he was a member of the clergy, having either walked with Jesus himself and been at the last supper as an Apostle or having been ordained through the prayer of the Apostles and laying on of hands in Acts 6:6.
When viewed in light of 1 Peter 20, it seems to be a pretty clear example of the Church intepretating scripture authoritatively in accord with God’s command. At a minimum, even if the injunction against personal interpretation of scripture applies only to prophetic works in the Bible, the precident for the existence of some interperative authority has at least been set.
