In addition to this feast, we also celebrate at Saint Thomas:
‚ñ∫The Conception of the Blessed Virgin Mary on December 8
‚ñ∫The Feast of the Annunciation on March 25 (in 2012, it falls on the same day as the Fifth Sunday in Lent)
‚ñ∫The Visitation on May 31
‚ñ∫The Feast of Saint Mary the Virgin on August 15
A 12:10 Mass in honor of Mary is offered once a month in the Chantry Chapel (Lady Chapel), usually but not always on the first Saturday.
There is much on this website with regard to Mary, especially in the Sermon Archive, where, among many other sermons, you will find these: by Fr Mead in 2010, by Fr Stafford in 2009, by Fr Austin in 2008, by Fr Andrew in 2007.
