I know what you mean however, many of us Protestants agree with Martin Luther that Church Tradition often contradicts the Word of God. Tradition sometimes troubles me. No Church can give me fullness of my faith. Romans 8:9 says, "If any man have not the Spirit of Christ, he is none of His." Spiritual Church is "invisible unity" which assumed to be imperfectly displayed, visibly: some denominations are less accepting of others, and the basic orthodoxy of some is questioned by most of the others. At the instant of our conversion, we become "eternal members" in the universal (catholic) church of Jesus Christ, based solely on His merit and grace.
Denominations separate; the word of God unites. That is the importance of IT IS WRITTEN being our standard and law.
God gave His word, His word is God. When He gives His Law for the Promised Land, He expects all to follow it. There is one law for all scripture says. The God of the whole earth shall He be called. If we refuse to follow those words, we do not have the true God. Jesus said to live by every word of God. When we follow Him in being obedient unto death, we have his righteousness. Only sins forgiven and forsaken is true repentance toward God. The Holy Ghost is the Spirit of Truth. Truth requires a word.
Deuteronomy 6:25 "And it shall be our righteousness, if we observe to do all these commandments before the LORD, our God, as He hath commanded us."
Jeremiah 15 and Ezekiel 14 go against most Christian theology.
Jeremiah 15:1 "Then said the LORD unto me, Though Moses and Samuel stood before Me, yet my mind could not be toward this people: cast them out of My sigtht, and let them go forth."
Ezekiel 14:12 - 21 God speaks about bringing judgments
14:20 Though Noah, Daniel, and Job, were in it, as I live, saith the Lord GOD, they shall deliver neither son nor daughter; they shall but deliver their own souls by their righteousness.
The goal is to be followers of Christ, living as He lived.
