Compare the Tridentine Mass prayers to the Novus Ordo Mass prayers. 

If you want to claim the TLM clearly communicates the understanding of Mass at one point in history, you can also say the Novus Ordo communicates the understanding of the Mass circa 1970, when it was promulgated. How arrogant to think Catholics didn't understand the Mass (as much as one can with our human intellects) until 1970!

If we understand the Mass so much better now post Vatican II than pre, why is it most Catholics choose to sleep in on Sunday mornings?  If they really understood the power of the Mass they would want to go as much as they could.
