Buddhism is older than Christianity. There are several religions and concepts that are most unChristian that are far older and even more widespread than Christianity. I mean, how many superstitions have been kicking around the globe for thousands of years?
WRONGO BUCKO, the Buddha does not predate Christ.
Furthermore nothing that the Buddha taught is adverse in any way to the teachings of Jesus.
One thing that did come along before the appearnce of Christ, Zoroatrianism, maybe rhw oldest 'religion' and from whom the Hebrews took some of their traditions during their captivity in Babylon.
The Zoraoastrians believed man was immortal until about 12,000 years ago when death and hell appeared upon Earth. Jesus is famous for conquering death and hell by his example of sacrifice and resurection from the dead.
An intersting story is that of one Zoroastrian king who predicted the birth of Christ and was most likely the reason for the Magi's appearance at the birth of Christ.
He had been a mere sherpard boy in the hills of Persia and had experienced a vistit of angelic hosts, much as the shepards who attented Christ's birth in Bethlehem, in a short span of twenty years he advanced from lowly shepard boy to the ruler of Babylon, ruler over many nations. At about the time he had the angelic visit, a prophet of Israel foretold the conquering and exile of the Hebrews becaused they had not followed God's instructions.
Abraham the patriarch of 'God's chosen people, paid tythes to Melchizedek, the king of Salem (Jerusalem, city of peace) and the Bible said Melchizedek and all his people 'had no beginning and no end', meaning they were immortals.
The Vedas of India and Hinduism predate Christ in the chronological orderof Earth time.
So does Greek mythology and who had a temple built to the 'unknown god."
The teachings of Lao Tsu predate christ but is more philosophical that religious although Lao said he learned his wisdom from immortals.
Recently a book has been written "Christ the Eternal Tao" with the meaning that 'tao' means 'way' and if fact when Jesus said I am the way, the truth and the light that He meant He was the physical embodiment of the Tao.
There is only one religion that is unchristian other than satanism that is islam, they are one and the same.
