Awesome! Reverence. Sense off the sacred. However, I think he meant to have said that this Latin Mass has been around since the 1500s.
It’s largely the same as the Roman liturgy of the 6th Century or so. Trent mandated it throughout the Western Church in the 16th Century.
No he meant it. 1500 years is a conservative estimate of the form of the liturgy. If you examine the names listed in the Canon, it is like a family prayer, where each saint is added as they were martyred.
When I was a child we added names to our night time prayers as they were born. So it started with my parents, and then each sibling was added. And then as the children grew they added their aunts and uncles and cousins as they were born. The prayer became a living family tree.
The same can be said for the Canon of the mass. If you look at the names, the liturgy goes all the way back to Peter.
For example, Just prior to Consecration: “Having communion with and venerating the memory, first, of the glorious Mary, ever a virgin, mother of Jesus Christ, our God and our Lord: likewise of blessed Joseph, spouse of the same virgin of Thy blessed apostles and martyrs, Peter and Paul, Andrew, James, John, Thomas, James, Phillip, Bartholomew, Matthew, Simon and Thaddeus; of Linus, Cletus, Clement, Sixtus, Cornelius, Cyprian, Lawrence, Chrysogonus, John and Paul, Cosmas and Damian”
and then after Consecration:
“To us sinners, also, Thy servants, who put our trust in the multitude of Thy mercies, vouchsafe to grant some part and fellowship with Thy holy apostles and martyrs; with John, Stephen, Matthias, Barnabas, Ignatius, Alexander, Marcellinus, Peter, Felicitas, Perpetua, Agatha, Lucy, Agnes, Cecilia, Anastasia,”
So based upon this DNA, if you look at who these people were and when they lived, with the view that the canon was a living family tree of the Family of God, it is obvious that the mass is much older than 1500 years.
