ISB ~ 2 Peter 1 v20

one’s own interpretation:The Spirit who inspired the prophecies of the OT is alone capable of interpreting them. By contrast, merely human intelligence can never ascertain their proper meaning without the divine assistance of the Spirit. The ramifications of this teaching are implied rather than stated, for Peter does not identify those who are authorized to give a correct interpretation of Scripture. Some contend that every believer who possesses the Spirit is automatically qualified for this task, but no such teaching can be found in the NT. On the contrary, we learn from other passages that the Spirit guides the Church into all truth through her apostolic leaders and their successors (Jn 14:26; 16:13), who serve as teachers and guardians of the Christian faith (1 Tim 6:20; 2 Tim 1:14; 2:2). This explains why Peter, being an apostle, expects readers to accept his teaching on Scripture as authoritative and reliable, whereas the false teachers among them are denounced for twisting its meaning (2 Pet 3:15-16) (CCC 104, 109-14). See note on Jn 14:26.
