Melkite Catholic Archbishop Hilaron Capucci, released from an Israeli prison Nov. 4, was assigned to visit Melkite communities in Latin America after he had an audience with Pope Paul VI last week.

The archbishop and His Beatitude Maximos V. Hakin, patriarch of Antioch and spiritual head of the Byzantine Rite Church, visited the pope. Earlier this year, the pope interceded on Archbishop Cappucci's behalf by issuing a formal appeal to Israeli President Ephraim Katxir to release the archbishop on humanitarian grounds.

Archbishop Capucci, former head of a group of 4,500 Arab Melkite Catholics in the Israeli-occupied West Bank of the Jordan River, was convicted in 1974 of smuggling guns and explosives from Lebanon to Palestinian guerrillas in the West Bank. His assignment to a post outside the Middle East was thought to be a condition of his release.

Bishop William Philbin of Down and Conor in Belfast, rejected an invitation to attend a peace rally last week in honor of Betty Williams and Mairead Corrigan, who recently received the Nobel Peace Prize for their work in launching a movement currently called the Peace People.

Another leader of the peace movement, Ciaran McKeown issued a public apology to Bishop Philbin for charging the bishop with "inactivity" in the search for peace in Northern Ireland.
