Interesting stuff there. Medieval. Love it.
"The Low Mass derived out of the celebration of private Masses, a practice that can be traced back to the Patristic period."
Eh wha?????
When I speak of private Masses during the Patristic period I do not mean that they were recited as todays Low Mass. Rather, I am referring to Masses other than the communal parochial Mass that were celebrated in private chapels for one reason or another. The Low or recited Mass was definitely a development from the Middle Ages.
