The 31st International Eucharistic Congress was held in Dublin in 1932, that year being the supposed 1,500th anniversary of Saint Patrick's arrival. Ireland was then home to 3,171,697 Catholics, about a third of whom attended the Congress. It was noted in "Time Magazine" that the Congress' special theme would be "the Faith of the Irish". The massive crowds were repeated at Pope John Paul II's Mass in Phoenix Park in 1979. The idea of faith has affected the question of Irish identity even in relatively recent times, apparently more so for Catholics and Irish-Americans. Today the majority of Irish people in the Republic of Ireland identify as Catholic, although church attendance have significantly dropped in recent decades. In Northern Ireland, where almost 50% of the population is Protestant, there has also been a decline in attendances.
