Archbishop Diarmuid Martin of Dublin has confirmed that Pope Francis, or his successor, will visit Ireland in 2018 for the World Meeting of Families. Archbishop Martin said that when he discussed the issue of visiting Ireland with the Pontiff, Pope Francis said: "'I will come', and he said, 'if I don't come, my successor will come.'" As well as Dublin, the Pope would probably visit Northern Ireland to complete the 1979 historic pilgrimage of St John Paul II, when rising tensions in the North made a visit there impossible. The Irish Catholic said Archbishop Martin made his remarks in an interview with the Irish Independent. The Irish Catholic said that a "well-placed Vatican source" confirmed that "all the indications from Rome are very positive about this". "It would obviously be the hope that the Holy Father would make a visit to Northern Ireland and, perhaps, some other parts of Ireland, since many Irish Catholics will want to have an opportunity to attend Mass with Pope Francis," the source told the Irish Catholic. Speculation about a papal visit began in September, after Pope Francis announced in Philadelphia that Dublin would host the 2018 World Meeting of Families. Popes have presided at all but two of the eight meetings held since the first meeting in 1994. However, a spokesman for Archbishop Diarmuid Martin of Dublin said that "speculation in the Irish Catholic newspaper concerning locations etc, quoting unnamed Vatican official are completely without foundation”. The spokesman added: "If a papal visit were to happen to coincide with the World Meeting of Families in Dublin in 2018, confirmation of such a visit would not happen until 2017, at the earliest."
