The Offices of Morning and
Evening Prayer are recited according to the 1928 Book of Common
Prayer, with enhancements from Canon Charles W. Douglas Monastic
Diurnal.
The Mass is celebrated according to The American
Missal. At Sung Masses, the Missal Propers are taken from The
English Gradual of Burgess.

the relationship between The American Missal and The Book of
Common Prayer, please read the article at the following link:
