Concerning ‘sola scriptura’, let’s consider several verses (these verses were all referenced on Catholic
Answers---catholic.com):
“I commend you because you remember me in everything and maintain the traditions even as I have delivered them to you” (1 Cor. 11:2).
Oral teachings are very important…can you demonstrate that this has changed after the end of apostolic era?
“Follow the pattern of the sound words which you have heard from me, in the faith and love which are in Christ Jesus; guard the truth that has been entrusted to you by the Holy Spirit who dwells within us” (2 Tim. 1:13-14).
“So then, brethren, stand firm and hold to the traditions which you were taught by us,
either by word of mouth or by letter.” (2 Thess. 2:15, emphasis added)
Both oral and written teachings are important, the NT gives no indication that Christianity is a religion of the book (alone).
“You, then, my son, be strong in the grace that is in Christ Jesus, and what you have heard from me before many witnesses entrust to faithful men who will be able to teach others also” (2 Tim. 2:1-2).
If after the apostolic era, the Bible alone would suffice, why did Paul believe that the continuation of sound doctrine required special teachers entrusted with the deposit of faith?
“First of all you must understand this, that no prophecy of Scripture is a matter of one’s own interpretation, because no prophecy ever came by the impulse of man, but men moved by the Holy Spirit spoke from God” (2 Peter 1:20-21).
“‘Though I have much to write to you, I would rather not use paper and ink, but I hope to come to see you and talk with you face to face, so that our joy may be complete” (2 John 12).
The written word was not enough, John wanted to teach them more orally.
“…and came and dwelt in a city called Nazareth; that it might be fulfilled which was spoken through the prophets, that he should be called a Nazarene.” (Matt. 2:23, ASV).
It’s interesting that this prophecy can not be found in Scripture…Matthew must have been relying upon the oral teachings of the prophets that was passed down. Also on this note…obviously the prophets spoke for God, but do you think that all the words of every prophet God sent is recorded in the OT? Were the words that are not recorded unauthoritative?
“…but if I tarry long, that thou mayest know how men ought to behave themselves in the house of God, which is the church of the living God, the pillar and ground of the truth.” (1 Tim. 3:15, ASV).
The Church, not the Bible alone, the Church is the pillar and foundation of truth…but how can it remain so if the church can not agree what truth is (on many issues)? Look how splintered Christendom becomes when apostolic succession is rejected. (I.e. Protestantism).
The Council of Jerusalem shows an authoritative church (in Acts 15) making a decision relevant to that time binding on all the faithful…can you demonstrate that this authority vanished with the death of the apostles? If you assume that Christianity’s sole authority became the Bible after the apostles died, how can you know this for sure?
(Edwin: I don’t know for sure that this is your position…so sorry if I’m assuming).
