The Bible asks us to submit to authority but the Lord is still our Shepherd, Christ is and always will be, and His teachings cannot be perverted by Church leaders.
We have the freedom to disavow church leadership when it betrays the teachings of Christ, which is why we are commanded by Christ to read for ourselves the Bible and understand when the leadership goes astray.
Let read more of the Hebrews and Ephesians passages that you have referred to;
" 7 Remember those who rule over you, who have spoken the word of God to you, whose faith follow, considering the outcome of their conduct. 8 Jesus Christ is the same yesterday, today, and forever. 9 Do not be carried about[c] with various and strange doctrines. For it is good that the heart be established by grace, not with foods which have not profited those who have been occupied with them. " -- Hebrews 13"1 And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers, 12 for the equipping of the saints for the work of ministry, for the edifying of the body of Christ, 13 till we all come to the unity of the faith and of the knowledge of the Son of God, to a perfect man, to the measure of the stature of the fullness of Christ; 14 that we should no longer be children, tossed to and fro and carried about with every wind of doctrine, by the trickery of men, in the cunning craftiness of deceitful plotting, 15 but, speaking the truth in love, may grow up in all things into Him who is the head—Christ— 16 from whom the whole body, joined and knit together by what every joint supplies, according to the effective working by which every part does its share, causes growth of the body for the edifying of itself in love." -- Ephesians
Each of us individually must be mature and not submit to blind obedience, for God has given us eyes to see by His Words.
Just so you know, radical Muslims will cut off the heads of Protestants, Catholics, and Orthodox Christians just the same.
You denied that you would give any human any obedience. That is unScriptural, and is as "cultish" as anything you accuse us of doing. It's the cult called "me, myself, and I are the final authority for all of us".
That isn't what the Bible teaches. Not even close.
