Where in scripture does it authorize any man to kneel before a statue, or to pray to a dead person, or to sing praises to Mary?
The scripture clearly condemns such practices. So if I have my choice between the Word of God or the traditions of men, I'll bank my eternal destiny on the Word of God alone.
Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye. (Mark 7:13 KJV)
It was the Holy Spirit that laid out the cannon of scripture. Those who chose that cannon did so at the leading of the Holy Spirit, who was determined to preserve his word by any means.
I will worship toward thy holy temple, and praise thy name for thy lovingkindness and for thy truth: for thou hast magnified thy word above all thy name. (Psalms 138:2 KJV)
Jesus prayed for all who would believe through the testimony of the Apostles.
The NT is that testimony for those who came after the Apostles' era.
Therefore, scripture has supreme say in the church as the words of the Apostles, upon whom the church was built, with Christ the chief cornerstone.
It is irrefutable.
Those either are or are not the words of Christ.
