The above is exactly what the author wrote, leading one to believe this story originates within the Bible. There is nothing even remotely mentioned in the Bible regarding this.
As for the New Testament coming from tradition, that is blatantly false:
2 Timothy 3:16 16 All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness,
2 Peter 1:19-21 19 We also have the prophetic message as something completely reliable, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts. 20 Above all, you must understand that no prophecy of Scripture came about by the prophet’s own interpretation of things. 21 For prophecy never had its origin in the human will, but prophets, though human, spoke from God as they were carried along by the Holy Spirit.
Ah, OK. If that is your point, I agree.
2 Timothy 3:16, 2 Peter 1:19-21
The Holy Scripture indeed is all God-inspired, profitable for the formation of the clergy, completely reliable and should not be interpreted privately. This however does not negate the fact that before Sts Mathew, Mark, Luke and John wrote the gospels, they knowledge about the ministry of Jesus was in the form of Catholic Tradition.
