The church building took almost three years of renovation work before it was suitable again for the worship of God through the old Latin liturgy. Bishop Finn offered the dedication Mass on October 26, 2008 and reconsecrated the church because it had been unused for many years. All Masses and liturgical ceremonies have now been moved from Our Lady of Sorrows church, where the old Latin Mass has been offered since 1990, to the beautiful new/old Oratory.
