It's pervasive throughout the NT and foreshadowed in the OT -- for those who have the eyes to see and ears to hear!
I think you are a very smart Lady..but I do think that it is always wise to read the scriptures carefully before making statements about them
The OT priesthood was a type of Christ.. He offered animal sacrifices for the sin of men.. The priest foreshadowed the final Priest jesus Christ.. who offered Himself ..the perfect lamb for our sins..
The priest was a type of Christ.. the lamb was a type of Christ. The entire OT is written about Christ..all of the canonical books are Cirhstocentric..
In the gospels , which are about the life of Christ before the foundation of the church ..speak of the priesthood..but what Jesus says of them is not flattering , it was the leaders of the Jews that brought jesus to be tried and killed
If one reads the NT formation of the church , there is no role of priesthood.. the sacrifices were ended ..Christ was the final sacrifice . There is no more sacrifice for sin.. there is no longer a need for a priesthood..and so there is none allowed for
