Geevee, listen to the language of a ritual sacrificial death of a man followed by eating his flesh and drinking his blood..............This, like much of Biblical folklore harkens back to Stone Age tribal purification and communion rites.
The Bible is almost completely based on pagan and astrological precedents.
Cleverly the Roman church happily sanctified as much pagan belief as it could to adopt as many pagan believers as possible and take them under its catholic umbrella in the third and fourth centuries. Later, having absorbed pagan folklore, it banned and destroyed all non Roman Catholic texts and forbade all non Roman Catholic ritual condemning it as pagan in the fifth century.
Et voila, Christianity!
