An association of Roman Catholic faithful dedicated to the preservation of the “Ancient form of the Roman Rite” or the “Extraordinary Form of the Roman Rite”, as a legitimate use of Holy Mother Church’s Great Liturgical Patrimony. The Society includes lay faithful drawn from every age, group and walks of life as well as clergy and religious members who “continue to adhere with great love and affection to the earlier liturgical forms.” (Pope Benedict XVI, Motu Proprio Summorum Pontificum of 2007)
