The Bible IS the sole source of authority of faith and practice. That dose not mean that we shouldn’t examine and learn from the writings of other great Christians. What it means though, is that if and when writings and practices and teachings that come from fallible human beings contradict God’s Word, His Word is always right over anything any man or woman writes. It’s just that simple.
Actually the Word of God is the sole source for faith and practice, not the bible alone, therein lies the difference.
Yes, it's just that simple. Whatever you read the Bible to mean is always right. And whatever I read it to mean is alwasy right, too. Even when we disagree.
