Passage: James's time in France had exposed him to the beliefs and ceremonies of the Roman Catholic Church; he and his wife, Anne, became drawn to that faith. James took Catholic Eucharist in 1668 or 1669, although his conversion was kept secret for almost a decade as he continued to attend Anglican services until 1676. In spite of his conversion, James continued to associate primarily with Anglicans, including John Churchill and George Legge, as well as French Protestants, such as Louis de Duras, the Earl of Feversham.Growing fears of Roman Catholic influence at court led the English Parliament to introduce a new Test Act in 1673. Under this Act, all civil and military officials were required to take an oath (in which they were required to disavow the doctrine of transubstantiation and denounce certain practices of the Roman Church as superstitious and idolatrous) and to receive the Eucharist under the auspices of the Church of England. James refused to perform either action, instead choosing to relinquish the post of Lord High Admiral. His conversion to Roman Catholicism was thereby made public.King Charles II opposed James's conversion, ordering that James's daughters, Mary and Anne, be raised in the Church of England. Nevertheless, he allowed James to marry Mary of Modena, a fifteen-year-old Italian princess. James and Mary were married by proxy in a Roman Catholic ceremony on 20 September 1673. On 21 November, Mary arrived in England and Nathaniel Crew, Bishop of Oxford, performed a brief Anglican service that did little more than recognise the marriage by proxy. Many British people, distrustful of Catholicism, regarded the new Duchess of York as an agent of the Papacy. James was noted for his devotion. He once said, "If occasion were, I hope God would give me his grace to suffer death for the true Catholic religion as well as banishment."
