The context of 2 Peter makes clear this means scripture comes from the Holy Spirit not from the personal opinions of the Prophets who pronounced it. Nothing hear says one should regard solely on another to interpret it for them. More on point is 1 Corinthians:
"these things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God. For who knows a person's thoughts except the Spirit of that person which is in him....Now we have received not the Spirit of the world but the Spirit who is from God that we might understand the things freely given us by God. And we impart this in words not taught by human wisdom but taught by the Spirit interpreting spiritual truths to those who are spiritual." 1 Cor 2:10-13
I have read ALL of Scripture, many many times and have no agenda, certainly not a Church driven one. I seek God not earthly worldly power for an institution.
