Portadown native Fr Joe McKeever died at Craigavon Area Hospital on Saturday morning.
The retired priest has been described as a “great character” who was well-known right across Co Armagh and beyond.
Fr McKeever taught at Drumcree High School for a number of years before he entered the priesthood, when aged in his 40s.
Among those paying tribute following his passing was Fr Paddy McCafferty, parish priest at Corpus Christi in Ballymurphy.
The west Belfast priest said: “Joe, originally from Portadown, was a late vocation having taught in Drumcree High School for some time. He was in his early 40s when he came to Maynooth to study for the priesthood. He was my next door neighbour for a while back then.”
