And yet we are MEMBERS of His body.
Eph. 4:11-12 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; 12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
Sorry, but I don't understand your point. Yes, there are people God has put in place for teaching and so on, but He has also said that to trust Him is to please Him, that without faith it is impossible to please Him. So, when I take Him at His word, that He will guide me into all truth through the presence of the Comforter, and do so in the same manner that Paul recommended as being more noble than just listening to him, how is that an insult or denigration of anyone else? You and I, and all other humans can always get things wrong. God never will. That's why my trust is in Him rather than in humanity.
My statement of never is not a statement that I never have read a theologian so in some way it is an overstatement of what I meant.. It's been my experience with them that they can take the simplest and clearest revelations from God and make them almost unrecognizable through over analysis and through human reasoning. When we read the Gospels we see that Jewish theologians did this a lot. They had almost completely corrupted the faith of the Jews by the time of Christ.
I'm not saying I never read anything outside of the Bible, but everything I read I take to the Bible and my heavenly Father for verification. I have yet to meet a human being who is a faithful and loving as He is. Therefore, I see no good reason for placing my trust in someone other than God. It is this experience that has led to me to no longer reading theologians. My entire purpose in studying the Bible is to know God, therefore His word is the best possible place for me to do that. Reading about His word, is not the same as reading His word that are filled with the power of life to the soul.
I look at this much like David did. He said, Thy word is a lamp unto my feet and a light unto my path. What David didn't say is just as important, in my estimation. He didn't say, what other people say about God's word is a lamp to his feet and a light to his path. He trusted God to be the light by which he lived his life. And since God said David was a man after His own heart, well, I will rest in that.
