An Explanation of the Mass

Bottom line: the Mass is a sacrifice.

The Mass is not predominately a bible study; it is a sacrifice. At Mass, just as in the Old Testament, worshiping God is performed through a sacrifice. In the Old Testament an animal was sacrificed on the altar to God. In many Jewish rites, that animal was then eaten in a communal meal by all to forge a covenant between God and His people. An example is Passover. The lamb was sacrificed, eaten, and then, true to God’s covenant, the first born son of those participating in the Passover was saved.

sacrifice -- communal meal -- covenant union

The sacrifice being re-presented (not represented) on the altar at Mass is Jesus. But, just as at the Last Supper, Jesus is in the form of bread and wine. Jesus is the new Passover Lamb re-presented in a bloodless sacrifice. We communally eat the meal. And remain in covenant union; the promise that God makes with humanity that He will forgive sin and restore fellowship with those whose hearts are turned toward Him.
