In fact if the information gleaned from a copy of Buddhist Scriptures, belonging to the leading Buddhist teacher of ChiangMai Province in Thailand, is correct then it would seem that Buddha may have even believed that a Holy One would be born one day that would be the savior of mankind.(image from book below)
***Perhaps, like for the old testament prophets & jews, it will be accounted to him as righteousness that he believed. He would have been a christian...
It has been suggested by others that maybe Buddha was saved. After all, as I said earlier Buddha did not start a religion that worshiped him, his followers did.
The question that remains to be asked is, did Buddha reject any worship of him during his life as Paul did?
Remember Paul and Barnabas both tore their cloths and begged the people not to worship them when he healed the lame man by telling him to get up and walk in Jesus name.
