The Eucharistic Sacrament is, in many churches,
central to their worship,
but why?

We are told that
The Eucharist is the meal in which regular bread and wine become the figurative body of Christ.
He was said to have taken pieces of bread and offer them up as his body.
The wine is representative of his blood.

There is a whole lot of magic associated with transformation
from bread and wine to body and blood through priestly words
and a conception that it is through eating these
eternal salvation is assured.
Here is forgiveness of sin!
Here is eternal life!
Here is peace!

Yet, and crucially to the church,
here is control, domininion,
priestly power.
