Fragmentary evidence that convinces some scholars, not others, from
records of the Mar-Thoma Church in India. Two records show either a 6 or and 8
(as I recall)
year stay over there when Jesus was in his early 20s.
Whne the Brit missionaries arrived in India to witness to the Xtian faith they
found the Mar-Thoma Church already there, apparently starrted by Thomas after
the resurrection. No NT, just the old. And a few reports that Jesus had visited
there even earlier.
Not my field of expertise. But I'll ask a couple folks who would know more about
it.
