77 GRACES DERIVED FROM PARTICIPATION AT THE MASS OF ALL AGES
One Holy Mass devoutly heard will do more to mitigate the pains of Purgatory than any act of penance, however difficult of performance.
This is the sixty-seventh of at least 77 Graces derived from participation at the Holy Sacrifice of the Mass - the Mass of All Ages - the Latin Mass of the Roman Rite which
was decreed to be said "in perpetuity" by Pope Saint Pius V
in codifying the infallible decrees of the dogmatic Council of Trent.
These graces are taken from Father Martin von Cochem's
Explanation of the Holy Sacrifice of the Mass with an
imprimatur by New York's Archbishop Michael Augustin
on June 24, 1818 during the Pontificate of Pope Pius VII.
