 The Apostles' Creed is one of the earliest known professions of Christian faith, and was used as a baptismal confession in Rome as early as the second century of the Common Era.Over the chancel arch is inscribed the Kyrie (Kyrie eleison..., Christe eleison..., Kyrie eleison...; Lord have mercy..., Christ have mercy..., Lord have mercy...), another of the most ancient liturgical elements of Christian worship, used perhaps even by the very first Christian communities.The liturgical elements of the ancient church, combined with the majestic architecture of the medieval church lend contemporary worship a palpable solidarity with the communion of saints, all those who have given their lives to Christ throughout the ages.
