Ok if you read the book, The Shape of Sola Scriptura, then you would know that original reformers, accepted the first eight ecumenical councils as authoritive. That reformers like Luther and Calvin were Christian Humanists who studied the church fathers, history, culture and biblical languages. If you study a movement called the “Chrisitan Connection” in american history. You will see that “sola scriptura” was redefined as the Bible Alone is the sole source of authority for the believer. This thread is about the modern american definition of Bible Alone that is being discussed in this thread.
Is that definition biblical?
2 Timothy 3:16
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness,
In context, all scripture only refers to the OT which Timothy learned as a child.
1 Timothy 3:15
if I am delayed, you will know how people ought to conduct themselves in God’s household, which is the church of the living God, the pillar and foundation of the truth.
It was the church as the “pillar and foundation of the truth” that determined the NT cannon which was done in council around 399 AD, about 75 years after Nicea.
For the first 40 years or so, the church had NO written NT, all was oral until the letters, were written, and then the gospels. The appostles taught doctrine to those that replaced them. This doctrine is recored in the church fathers.
2 Thessalonians 3:6
Now we command you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walketh disorderly, and not after the tradition which he received of us.
2 Thessalonians 2:15
Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.
