Was Jesus a Hindu saint?
If you are Muslim you believe Jesus was only a prophet. If you are Jew "Jesus was been just one the most influent false prophet". If you are atheist Jesus was only a good man. If you are Hindu, why Jesus can't be an Hindu saint?
You can be Christian or not but is undeniable that the figure of Jesus has influenced the whole of humanity. So every one see is figure giving a proper interpretation.
Thomas is traditionally believed to have sailed to India in AD 52 to
spread the Christian faith, and is believed to have landed at the port
of Muziris, Tamilakam (modern-day North Paravur and Kodungalloor in
modern-day Kerala state) where there was a Jewish community at the
time.
So is possible that with the passage of time differente culture and tradition was mixed.
Jesus was a Hindu person. His religion was Hinduism
As far as I know there are no historical documents that affirm this (that Jesus was from India). So in my opinion, when first Christians went to predicate in India the naive population reinterpreted is figure.
