In practice and in attitude, are we forgetting that the Eucharist is a covenant?
Our Lord gave us his Eucharist by referring to his Blood as "the Blood of the new and everlasting Covenant." With that declaration he echoes Moses' words in ratifying the ancient Mt. Sinai Covenant. "Behold the blood of the Covenant!" [Exodus 24:8]
The Mt. Sinai Covenant took place with God DEMANDING reverence for his untouchably holy mountain at whose foot he decreed an altar of piled stones unmarked by human tools.
The Mt. Sinai Covenant— just as any covenant— is a life-and-death mutual transaction, by which both parties in the Covenant vow to lay their lives on the line for each other.
By our casual liturgical manners today, we fail to let the New and Everlasting Covenant speak of the implicit, solemn and dangerous demand Christ is requiring of us by giving us his Eucharist AS a covenant.
We do not "receive" the Eucharist with right intention if we fail to understand that it is a COVENANT, that is, a binding two-way "faithful-unto-death" vow. One never “receives” a covenant. A covenant is always agreed to and entered.
ALL SOLEMNITY is owed to the liturgical celebration of the Eucharist, the Mass, simply by the very nature of a covenant.
