And here we have the same debate going that the Church fathers, the authorities of their day, spent hours, weeks, months, years, their entire lives debating. That would include the New Testament patriarchs as well as the faithful men of God who shepherded the Church into the next centuries.
We see it in Paul's letters to the churches. Saved by the grace of God himself, he could not stop writing (and no doubt preaching and teaching) about that. But he was also a Jew raised in the devout Jewish tradition of the Law, and you also see his impulses to rescue and defend it now and then, not as the road to salvation, but as the way of edification and discipline as Christians. So you see his dichotomy as he respected those given authority in the Church while also being aware that some in authority were teaching false doctrine.
Paul wrote to the Ephesians (6:12): "For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms." NIV
And to the Corinthians he wrote: (2 Cor 11:14-15) "And no wonder, for Satan himself masquerades as an angel of light. It is not surprising, then, if his servants masquerade as servants of righteousness." NIV
Later Matthew (7:15-16) would quote Jesus as saying: "Watch out for false prophets. They come to you in sheep's clothing, but inwardly they are ferocious wolves."
And still later John would write: (1 John 4:1) "Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world." NIV
And ultimately all three, in different ways, would assure us that we have direct communication with God and need no mediator. I tend to be suspicious of ANY authority who presumes to dictate to the people what rules they must follow in order to be acceptable to Christ. I trust most those who teach as Paul wrote to the Phillipians:
(4:8)Finally, brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, dwell on these things. 9The things you have learned and received and heard and seen in me, practice these things, and the God of peace will be with you.
In other words, a true Christian authority will teach that God came in the flesh, died, was buried, and resurrected and in so doing paid for our sins and assured us of eternal life. He now, via the Holy Spirit, is with us and will lead us into all truth unto the end of the Earth. In my opinion, those given authority will use it rightly when they teach this and, more importantly, when they live this themselves. I am suspicious of those in authority who presume to take God's role and dictate rules by which the people must live by in order to be good Christians.
And at the same time I believe God loves all those and honors the pure heart in the more legalistic traditions too.
