Immaculate Conception Parish is an Apostolate of the Priestly Fraternity of St. Peter (FSSP) in the Diocese of Colorado Springs. Thus, the Parish uses the liturgical books that were in force in 1962. All parochial Sacraments are available according to the "Extraordinary" form of the Roman Rite, or the Traditional/Tridentine Latin Mass. These rights are granted to the members of the FSSP as well as to other priests staying in the houses of the Fraternity or exercising their sacred ministry in the churches of the Fraternity.
