The political, social and economic turmoil of the times of the early 19th century were all taken as signs that the Second Coming of Christ was imminent. The Catholic Apostolic Church was formed in 1835 to prepare for this event.
An elaborate and beautiful liturgy was devised, derived mainly from the Eastern Orthodox, Roman Catholic and Anglican Churches, and involving music, processions, rich vestments and incense.
Ordinations in the Church ceased in 1901. The last priest of the Edinburgh congregation died in 1958 and the congregation moved out, ending Catholic Apostolic worship in this building. The last Catholic Apostolic priest died in 1971 and all sacramental ministrations ceased.
