So why am I to believe these “ancient written history”'s about his adolescent years over the ones that have existed in the Christian world for most of the life of the Christian faith, or over Tradition which states he spent the time in Nazareth (a claim that scripture itself makes)?
I think you need to take to heart, first, that Our Lord Jesus says to “Prove all things”, to yourself.
At the same time, open your mind to the latest ancient written history such as the Lost Gospels, of Thomas, Judas, Mary Magdalene, even Peter!..the Dead Sea Scrolls, the Nag Hammandi, and other ancient religious texts, which have in our recent history, been “found” and brought to humanity’s base of known and practicing, religious ancient history manuscripts.
Try to have some faith, that all world religions are based on the Wise Religion, which is the Science of GOD, the belief in the Creator (history, through THOUSANDS of years, within the disciplic succesion of Brahmanism).
In this same way, you can dig further back into your open mind, and discover where the GOD/Wise Religion began?..the base foundation of all Christianity, Judaism, and Brahmanism’s offshoot, Buddhism, are based religions, with belief in the Creed (Correct Belief), as reality, of One Almighty GOD.
The Wise Religion as Catholism and Christianity, are foundation based in Brahmanism (simply, without the perversions or changes, to class/rites/schisms), and Buddhism is an offshoot of Brahmanism too…
There are 3 types of Buddhism and the Buddhism you are aware of is Mayavada (illusion) and this Buddha, broke away from the Brahmanism sects, because of what he considered were perversions of the original brahman…the disciplic succession scriptures, of GOD’s/Wise Religion, 2600 yrs. ago.
Buddhism (as one offshoot to Brahmanism) Lama monks and lay monk historians do not lie…(really, they follow GOD’s law, of not bearing false witness to anyone=Brahmanism) and their historical events were passed from oral tradition to written manuscripts, in order to preserve the history of the times…no more nor any less.
