By what are we converted? It is the word of God. Either read, or preached. But we are not converted by commentaries, expositories, the church, church manuals, councils, canons or creeds.
“20 Assemble yourselves and come; draw near together, ye that are escaped of the nations: they have no knowledge that set up the wood of their graven image, and pray unto a god that cannot save. 21 Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me. 22 Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else. 23 I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear. 24 Surely, shall one say, in the LORD have I righteousness and strength: even to him shall men come; and all that are incensed against him shall be ashamed. ”
Isaiah 45:20-24 KJV
“7 Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon. 8 For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD. 9 For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts. 10 For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater: 11 So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. ”
Isaiah 55:7-11 KJV
If you are trusting in the authority of the church, or the wisdom and teaching of man, you have abandoned the scriptures and your hope and faith is in vain. Jesus promised that He would give the holy Spirit in order to teach truth. Catholics love to point out the multitude of discordant doctrines that are in the world, and encourage everyone to trust in them, the catechism, or ultimately the magisterium. Them they attempt to make the point that Jesus's promise concerning the holy Spirit guiding into all truth was only for them. History has recorded that in order to encourage such submission to their authority, they have resorted to armed force and threats of violence and Inquisition. In other words, their own actions deny the very thrust of what they try to prove. In using force, they are in effect saying they no longer trust in the holy Spirit, but they have to help God by coercion.
Again, the word of God, even Jesus Himself, is God's selected vehicle through which salvation and sanctification is made effective.
"And the Word was made flesh..."
"Sanctify them through thy truth, thy word is truth".
“25 Husbands, love your wives, even as Christ also loved the church, and gave himself for it; 26 That he might sanctify and cleanse it with the washing of water by the word, 27 That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish. 28 So ought men to love their wives as their own bodies. He that loveth his wife loveth himself. 29 For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church: 30 For we are members of his body, of his flesh, and of his bones. 31 For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. 32 This is a great mystery: but I speak concerning Christ and the church. ”
Ephesians 5:25-32 KJV
“16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek. 17 For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith. ”
Romans 1:16-17 KJV
“3 According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue: 4 Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust. ”
2 Peter 1:3-4 KJV
