And I fell at his feet to worship him. And he said unto me, See thou do it not: I am thy fellowservant, and of thy brethren that have the testimony of Jesus: worship God: for the testimony of Jesus is the spirit of prophecy. Revelation 19:10
The fact is that scripture alone has the testimony of fulfilled prophesy to give it it's authority. Tradition, Catholic or otherwise, has none. The following is taken from Clarence Larkins book "Dispensational Truth". It well illustrates the authenticity of the scriptures, and why we should rely solely on them and not on the subjective traditions of men. Be a little open minded and see if it doesn't ring true!!
If I were to predict an earthquake in Philadelphia next year the chance would be 1 in 2 that it would occur. If I should add another prediction, that it would be on the Fourth of July, the chance is decreased to 1 in 4. And if I add another detail, that it will be in the daytime, the chance then becomes 1 in 8. And if I should add a fourth detail the chance would be 1 in 32. And if the details were 10 in number, the chance would be 1 in 1024.
Now there were 25 specific predictions made by the Old Testament Prophets bearing on the betrayal, trial, death and burial of Jesus. These were uttered by different prophets during the period from B. C. 1000 to B. C. 500, yet they were all literally fulfilled in 24 hours in one person. According to the Law of "Compound Probabilities" there was one chance in 33,554,432 that these 25 predictions would be fulfilled as prophesied. If one prophet should make several predictions as to some one event, he might by collusion with others bring it to pass, but when a number of prophets, distributed over several centuries, give detailed and specific predictions as to some event, the charge of collusion cannot be sustained. It is a fact that there were 109 predictions literally fulfilled at Christ's First Advent in the flesh. Apply the Law of "Compound Probabilities" to this number, and the chance was only one in BILLIONS that they would be fulfilled in one person.
The argument that Jesus employed to convince those two mourning disciples walking to Emmaus that He was "The Messiah," was the appeal to Prophecy "And beginning at Moses and ALL THE PROPHETS, He expounded unto them in ALL THE SCRIPTURES (0ld Testament Scriptures), the things concerning Himself." Luke 24:27. The two disciples were familiar with the things that had occurred the previous week at the arrest, trial, crucifixion and burial of Jesus, as well as the rumors of His resurrection. It was not difficult therefore for Jesus to take those things and by quoting from the Old Testament Scriptures show that they were just what the prophets had foretold would happen to the Messiah when He came. He reminded them that the prophet had said that the Messiah should be sold for 30 pieces of silver (Zech. 11:12), be betrayed by a friend (Psa. 41:9), forsaken by His disciples (Zech. 13: 7), accused by false witnesses (Psa. 35:11), be dumb before His accusers (Isa. 53: 7), be scourged (Isa. 50: 6), His garments parted (Psa. 22:18), mocked by His enemies (Psa. 22:7-8), be given gall and vinegar to drink (Psa. 69:21), not a bone of His body broken (Psa. 34:20), die with male-factors (Isa. 53:12), that the price of His betrayal should be used to purchase a "Potter's Field" (Zech. 11:13), and that He should be buried in a rich man's tomb. (Isa. 53 : 9.)
But Jesus did not stop with simply proving that the crucified Christ fulfilled all the requirements of prophecy. It was a long walk they had. Jesus joined them soon after they left Jerusalem for Emmaus, which was some 6 miles away, and so had ample time in which to outline the "Prophetic Portrait" of the Messiah. Turning to Gen. 22: 7-8, He pictured Isaac as a "Type" of Christ, and that God spared Abraham's son, but did not spare His own Son. He then called attention to the institution of "The Pass-over," and recalled the fact that in preparing the lamb for roasting, two spits were used, one thrust lengthwise through the body for support over the fire, and the other across the shoulders for turning, thus symbolizing the Cross on which the Lamb of God was suspended. He then reminded them that he (Jesus) had said in one of His discourses- "And I, if I be LIFTED UP, will draw all men unto me." John 12:32. And having thus refreshed their memory, He took them back to that incident in the history of the Children of Israel of The "Brazen Serpent," and pointed out that that was a type of how men are bitten with the serpents of sin, and need a Saviour, and how Jesus by being lifted up took the place of the "Brazen Serpent," and that all that look to Him in faith shall be delivered from the results of sin. Then Jesus spoke of the Prophet Jonah, and what befell him, and a recalled His own prophecy, which doubtless they had heard but had forgotten, that "As Jonah was three days and three nights in the whale's belly, so shall the Son of Man be three days and three nights in the heart of the earth" (Matt. 12:40), thus showing them that they should not have been surprised at the report they had heard that morning, that Jesus had RISEN FROM THE DEAD.
Is it any wonder that as Jesus thus went on outlining the "Prophetic Christ" and comparing Him with the "Historic Christ" they had known and loved, that their heart "BURNED WITHIN THEM" as He talked with them by the way, and opened up to them the Scriptures. Luke 24: 32. How easy a conundrum seems when we know the answer, and how simple the Scriptures become when we see Christ in them, for "the TESTIMONY OF JESUS" is the "SPIRIT OF PROPHECY." Rev. 19:10. That is, the Spirit and purpose of all Prophecy is to testify of Jesus. How important then is the study of Prophecy.
Now we have seen that there were 109 predictions of the Old Testament Prophets literally fulfilled at Christ's First Advent, but there are 845 quotations from the Old Testament in the New Testament, and 333 of these refer to Christ. They vary from types and figures that seem meaningless
unless you place Christ in them, to exact predictions that at times descend to the minutest details. The only books of the Old Testament not quoted in the New Testament are Ruth, Ezra, Nehemiah, Songs of Solomon and Obadiah.
Catholic Tradition, along with the literature of all the worlds religions have nothing to match the prophesy fullfilled just in the life of Jesus Christ. The other prophesies, which cover his second coming, the millenial kingdom. Law and justice in that kingdom, prophesies on the Coming Antichrist, his appearing and appearance, the false prophet, the beast of Revelation (Apocalypse) make the odds of fulfillment astronomical. Why should we trade in something sure for something that contradicts the scriptures at every turn?
