I do wish you would quit using the language of those who crucified Christ.
Scripture only isn't what the Bible says. The Bible says that new ideas cannot contradict scripture.
Isa 8:20 To the Law and to the testimony! If they do not speak according to this Word, it is because no light is in them.
Deu 13:1 If a prophet rises among you, or a dreamer of dreams, and gives you a sign or a wonder, Deu 13:2 and the sign or the wonder which he foretold to you occurs, saying, Let us go after other gods which you have not known, and let us serve them, Deu 13:3 you shall not listen to the words of that prophet or that dreamer of dreams. For Jehovah your God is testing you to know whether you love Jehovah your God with all your heart and with all your soul. Deu 13:4 You shall walk after Jehovah your God and fear Him, and keep His commandments, and obey His voice, and you shall serve Him and hold fast to Him. Deu 13:5 And that prophet or that dreamer of dreams shall be put to death, because he has spoken to turn you away from Jehovah your God, who brought you out of the land of Egypt and redeemed you out of the house of slaves, to thrust you out of the way in which Jehovah your God commanded you to walk. So you shall put the evil away from the midst of you.
2Ti 3:14 But continue in the things that you have learned and have been assured of, knowing from whom you have learned them, 2Ti 3:15 and that from a babe you have known the Holy Scriptures, which are able to make you wise to salvation through faith in Christ Jesus. 2Ti 3:16 All Scripture is God-breathed, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, 2Ti 3:17 that the man of God may be perfected, thoroughly furnished to every good work.
Act 17:11 And these were more noble than those of Thessalonica, in that they received the Word with all readiness of mind and searched the Scriptures daily to see if those things were so.
Mat 15:9 But in vain they worship Me, teaching for doctrines the commandments of men."
I completely agree with that.
And I agree with all the passages you quote here. But none of that teaches "Scripture alone", i.e. no bishops, no Sacred Magisterium.
