Missionaries from the Order of
Missionaries of the Sacred Heart (M.S.C.) arrived in 1898. In 1905, a pre-diocesan jurisdiction was established as
Mission sui juris of Marshall Islands, on territory split off from the then
Apostolic Vicariate of New Pomerania (mainly
New Britain, in the
Bismarck Archipelago of
Papua New Guinea). On April 5, 1923, the independent mission was suppressed, its territory being merged into the then
Apostolic Vicariate of Mariana, Caroline and Marshall Islands. On April 23, 1993,
Pope John Paul II split the former Diocese of Carolines-Marshalls into the
Apostolic Prefecture of the Marshall Islands and the
Diocese of Caroline Islands. In 2007, Father James Gould, apostolic prefect, resigned. Father Raymundo Sabio, a Filipino missionary, was chosen to succeed him. == Ordinaries ==
