Strange, I haven't read any commentaries that ask their readers to do that either...
You're basically rejecting the God given gift of the teachers in the body. God gave the Church TEACHERS my friend.
These teachers are not infallible, but to say that all of them corporately are not useful is just ridiculous.
Also how does the Holy Spirit determine truth from error for you? Does the Holy Spirit grant you an infallible understanding of the Scriptures magically, while everyone else is wrong? What gives you such a power that other believers do not have?
I never said I rejected all teachings as there are many that are word teachers that God has given us and not just socially acceptable traditionally taught teachers. Yes, the Holy Spirit is the only one who can give me pure understanding as I will not believe anyone unless the Holy Spirit confirms through the word that they are teaching truth or error. Many confess Jesus as their Savior and are Spiritual born-again, but yet teach in error because they just take it as face value of what they have been taught by others and continue to teach others in the same manner as they do not dig out truth for themselves. I'm sure you have heard the phrase being lead around like a bull with a ring in it's nose.The grace of God gives all of us his power and authority to be His servants as it is not us that speaks, but the Holy Spirit that speaks through us. I do believe that the Holy Spirit gives me an infallible understanding of scripture just as he gives others. Am I infallible, no, but the Holy Spirit that dwells in me is and if I need correction then the Holy Spirit will correct me.
1John 4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
1John 4:2 Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God:
1John 4:3 And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
1John 4:4 Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world.
1John 4:5 They are of the world: therefore speak they of the world, and the world heareth them.
1John 4:6 We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.
