Come and join us to celebrate the feast of this great saint and, arguably, the most influential thinker in Western thought. The Mass will be sung in Gregorian chant and it represents a unique opportunity to hear the sequence of St. Augustine, De profundis tenebrarum. Sequences are medieval liturgical hymns to be sung before the Gospel. They were almost completely eliminated after the Council of Trent (1545-1563) because, despite their undeniable orthodoxy, great beauty, and piety, their extra-biblical origin made them an easy target for the Protestant revolutionaries. Fr. Neely, our celebrant, is an Augustinian monk and enjoys the privilege of his order of using the ancient sequence on the feast day of their patron saint.
