[1] Catholicism, along with any other denomination not considered part of the Church of England and any non-Christian faiths, was outlawed in Bermuda, as in the rest of English territory, from the time of settlement (1609 to 1612).
Although the Roman Catholic Church began to operate openly in Bermuda in the 19th century, its priests were not allowed, at first, to conduct baptisms, weddings or funerals.
Mount Saint Agnes Academy, a private school operated by the Roman Catholic Church, and located within sight of the cathedral, opened in 1890 at the behest of officers of the 86th (Royal County Down) Regiment of Foot (which was posted to Bermuda from 1880 to 1883), who had requested from the Archbishop of Halifax, Nova Scotia as school for the children of Irish Catholic soldiers.
[2][3] The numbers of Catholics also began to increase from the 1840s onwards due to the encouragement of immigration of labourers from Portuguese islands, such as the Azores.
[4][5] St. Theresa's was consecrated in 1932, having been built on Cedar Avenue, in Hamilton, on land obtained in 1915 by Father Isaac Comeau.
