Why did the Bible not mention the biography of the thirty years the Lord Christ spent before His ministry? Did He go to China to study Buddhism as some say?
It was not meant for the Holy Bible to be a book of history.
If the Gospels were to mention all the events and the historical details “even the world itself could not contain the books that would be written” (John 21:25). The details of one day in the life of the Lord Christ on earth with all the teachings and miracles would alone need more than one book.
The intent of the Gospel is to be the good tidings of salvation, telling the history of our salvation.
Therefore the Gospels started by the miraculous birth of Christ from a Virgin, the angels involved in the story of the Divine birth, also the genealogy of Christ, and the fulfilment of the prophecies pertaining to His birth. Then they moved on to His baptism and the start of His ministry. As an example of His childhood, His meeting with the elders of the Jews and their astonishment of His answers (Luke 2:46)… was mentioned to point out His teaching abilities since His young age.
But the claim that He went to China is unfounded.
This claim has no support from the Bible history or tradition. Those who say that are anti-Christ whose purpose is to mislead the people that Christ took His teachings from Buddhism. Therefore it was proper for the Gospel to mention the surpassing knowledge of Christ since His young age so that the elders were astonished by His answers. He did not need to go to China or elsewhere.
The teachings of the Lord Christ are superior to Buddhism and to any other teaching.
Any learner can discover this unmeasurable superiority. It is not the place here to compare, but if there were a resemblance between His teaching and Buddhism, the Buddhists would have believed in Him.
The magnificence of the Lord Christ is not confined only to His teaching. Did He also take His majestic miracles from Buddhism?!
Did He take from Buddhism the raising of the dead, opening the eyes of the blind, the rebuking of the sea, walking on water, the feeding of the multitudes, healing the incurable diseases, casting out demons and the other countless miracles.
Did He take from Buddhism the Salvation that He offered to the world?
We should not let our imagination run about the thirty years prior to His ministry. It is enough to know that the Lord Christ started His public ministry according to the Law (Num. 4:3, 23 & 47; 1 Chr. 23:3) when He was thirty.
What we need to know about the story of Salvation is the ministry of Christ after His thirtieth year, added to that His Virginal birth and all the prophecies and miracles around it.
