A Pontifical High Mass in commemoration of the first anniversary of the canonical erection of St. Francis de Sales Oratory was celebrated by the Most Reverend Raymond L. Burke, Archbishop of St. Louis, on Sunday, July 16. On this occasion, His Grace also solemnly installed a relic of St. Prosper at the side altar of Our Lady.  St. Prosper, a fifth century saint, coined the phrase "Lex Orandi, Lex Credendi" meaning "Pray as you believe". This was the closing Mass of the National Convention of the Latin Liturgy Association, which took place at St. Francis de Sales Oratory that weekend. View Images
