A great video on the meaning of the mass.

 Fr. Mike Schmitz takes us through the Hebrew roots of the meaning of the Mass. He helps us to understand that the Mass is not a "show" to be watched, but is a sacrifice that we partake in. He points to the various points of the Mass which depict the sacrifice taking place. The points of the Mass wherein the sacrifice of Christ is re-presented to the Father as commanded by Christ, and the meaning of the sacrifices from both the Old Testament and the New.
