I’ve spent more than six months working, with Nicoline Greer from the Documentary on One team at RTE Radio 1, on making a 40-minute documentary called ‘From Belief to Unbelief’.

It charts the story of my journey from belief to unbelief, and also that of two fellow novices, John O’Sullivan and Declan Wynne, who entered the Marist Fathers’ seminary at Mount St Mary’s, Milltown, Dublin, in September 1980.

Of the twenty who entered that year, only three remain in religious life.  I left after nine years. Declan after ordination, having spent thirteen years in the order. John is the most recent to leave: he was a member of the order for some thirty years.

We each speak of the insights, realisations and key events in our personal paths starting with our sense of a call to the priesthood and religious life; entering the seminary; our challenges, questions and crises; our deeply personal and painful decisions to leave religious life; and our contented lives today as unbelievers.

The documentary is not only the personal story of three men: our lives may be seen as a microcosm for the transformation taking place in Irish society in the last 20, 30 or even 50 years. In the early 1980s there were some 40 seminarians in the Marist Fathers’ seminary in Ireland alone. Nowadays, there are no Irish seminarians in the order and Mount Saint Mary’s is no longer a seminary. The chapel which once reverberated to the sound of many young vibrant seminarians now lies silent and is rarely used. As recently as the early 1980s, the houses of the Marist Fathers in Ireland boasted full communities of priests, compared to the small and aging communities remaining today.

Thirty-two years after entering the order, I revisit the former seminary in the company of Father Denis Green SM, now in his nineties, who used to be my spiritual director.

Documentary maker: Joe Armstrong.

Production supervision by Nicoline Greer.
