SemperReformada, your thoughts regarding the OP?
Certain authors of the New Testament clearly cite oral Tradition to support Christian doctrine, in addition to old Testament Scripture. In some instances, they explicitly cite oral Tradition to support Christian doctrine, which, to me anyway, seems to undermine the doctrine/practice of sola scriptura. Certainly, for the apostles, oral Tradition must have been trustworthy when formulating and developing elements of the Christian faith. Examples of Jesus and the Apostles’ reliance on oral Tradition:
Matt. 2:23 - The prophecy “He shall be a Nazarene” must be an oral tradition. It is nowhere to be found in the Old Testament. This demonstrates that the apostles must have relied on oral tradition, otherwise…
Matt 23:2 - Jesus relies on the oral tradition of acknowledging Moses’ seat of authority (which passed from Moses to Joshua to the Sanhedrin). This is not recorded in the Old Testament.
John 19:26; 20:2; 21:20,24 - knowing that the “beloved disciple” is John may be inferred from scripture, just as, is the case with Mary being full of grace, according to non-Catholics, but it must be explicitly derived from oral tradition.
1 Cor. 10:4 - Paul relies on the oral tradition of the rock following Moses. It is not recorded in the Old Testament. Exodus 17:1-17 and Numbers. 20:2-13.
Heb. 11:37 - The author of Hebrews relies on the oral tradition of the martyrs being sawed in two. Yikes…This is not recorded in the Old Testament.
Jude 9 - Jude relies on the oral tradition of the Archangel Michael’s dispute with satan over Moses’ body. This is not recorded in the Old Testament.
Jude 14-15 - Jude relies on the oral tradition of Enoch’s prophecy which is not recorded in the Old Testament.
Ephesians - 5:14 - Paul relies on oral tradition to quote an early Christian hymn - “awake O sleeper rise from the dead and Christ shall give you light.”
Jude 14-15 - Jude speaks of the rebellious upstarts of his day, saying, “It was of these also that Enoch in the seventh generation from Adam prophesied, saying, ‘Behold, the Lord came with his holy myriads, to execute judgment on all, and to convict all the ungodly of all their deeds of ungodliness which they have committed in such an ungodly way, and of all the harsh things which ungodly sinners have spoken against him.”
Here is a tradition, (a prophetic revelation) - which was passed on orally for millennia before being captured first in a non-inspired written document (1 Enoch) - and then in an inspired document, in the New Testament. This clearly shows that the writers of the New Testament regarded oral tradition as divine revelation.
