Acknowlegement and celebration? Now there’s a secularist spin on an event in sacred history.
C'mon, read the scripture...Melchizedek certainly didn't perform a sacrifice...
There isn't a place in the Old Testament where bread and wine are used for any sacrifice...
Abram just killed a bunch of bad guys, recovered the lost valuables along with his kin and he was given food and drink afterwards...
You'll find nothing in the OT that describes otherwise...
