The island of Jersey remained part of the Duchy of Normandy until 1204 when King Philip II Augustus of France conquered the duchy from King John of England. The islands remained in the personal possession of the king and were described as being a Peculiar of the Crown. However, throughout the Middle Ages, the Catholic Church did not concern itself with overly political changes and the island continued to be part of the Norman diocese of Coutances. It was reluctant to come under the wing of the English church because it had many ties with Normandy: its language, which was much like that of the Normans; trade links; Norman customary law; and kinship to families in Normandy. of the 16th century. Here, the millennium cross of Saint Helier bears the Jèrriais inscription À la glouaithe dé Dgieu. The island embraced the French Calvinist form of Protestantism during the Reformation and the orders were received to remove all signs of Catholicism in 1547 with the Act of Dissolution of the Colleges and Chantries, which had been applied to Jersey in the Act of Uniformity 1549: numerous wayside crosses were destroyed along with religious statues and other symbols. In 1550 a Royal Commission visited the island to sell church property for the benefit of the crown; in 1551 Sir Hugh Paulet, a member of this Royal Commission, was made Governor of the island and so he returned with a Royal Commission addressed to himself to continue the task. The island remained under the diocese of Coutances until 1569.
In the 1790s, during the French Revolution, French Catholics took refuge in Jersey, allowed to hold services but not to proselytize. In the 1830s and 1840s the island's Catholic community knew growth with the influx of Irish labourers coming to work on major building projects such as the new harbour. Towards the end of the 19th century Catholic teaching and nursing orders — the De La Salle brothers, Jesuits and Little Sisters of the Poor — settled in Jersey. In 1894, the Jesuits bought a property called Highlands, which later became Highlands College. In 1917, the De La Salle Brothers founded De La Salle College, Jersey.
Today, Jersey is under the diocese of Portsmouth. There are eight Catholic churches on the island. However, there is a shortage of priests and workers and the Catholic Church there has therefore had to close two chapels and sell some of its churches. Minorities of the Catholic faith in Jersey are not negligible, as Mass in certain churches is regularly held in Portuguese and Polish and only occasionally today in French. Indeed, 6% of Jersey's population is Portuguese and among the 6% of Europeans there is a large Irish community and a considerable Polish community.
