The Stormont Executive has established a statutory probe into abuse committed in state and church-run institutions, but its remit does not cover criminal acts committed by priests outside of children's residential facilities.
Michael Connolly claims he was victimised for five years of his childhood in Donagh, Co Fermanagh, by parish priest Peter Duffy, who was later promoted to canon.
The deceased cleric was the uncle of the former Bishop of Clogher, Joseph Duffy, who was today heavily criticised for unsatisfactory responses to child abuse allegations and risky behaviour of priests in the diocese.
A watchdog review of the diocese, which straddles the border between the Irish Republic and Northern Ireland, found opportunities to prevent attacks in the past were consistently missed when concerns were raised.
Mr Connolly, who was also abused by members of the notorious McDermott family in Donagh as a child, said he was targeted by Peter Duffy between 1970 to 1975 and claims two other alleged victims have come forward since he waived his right to anonymity in 2011.
As today's report on the abuse in the Clogher diocese by the Catholic church's National Board for Safeguarding Children is anonymised, Mr Connolly said he was unsure if it had examined his allegations.
The 53-year-old, who now lives in Co Donegal, said it was time for the Executive in Northern Ireland to take responsibility for such investigations.
He believes more victims across Northern Ireland will speak out if a state inquiry is held, similar to those which uncovered decades of abuse in the Republic.
Mr
Connolly, who is head of the campaign group Clerical Abuse NI, has
accused the church and state of failing to protect their innocence and
ignoring their plight now.
"It is clear
that not only did the church fail to protect children, but so did the
state, which turned a blind eye to widespread child abuse over many
decades," he said.
"Only a proper public
inquiry can establish the facts, hold to account those responsible and
ensure that this can never happen again."
He
added: "The first and deputy first ministers (Peter Robinson and Martin
McGuinness) should show compassion and immediately set up an inquiry
into clerical abuse.
"Survivors should no longer be kept in agony."
The historical institutional abuse inquiry in Northern Ireland is being headed up by former judge Sir Antony Hart.
So far, almost 250 people have applied to shares their experiences to the inquiry team.
Sir Antony has insisted that the remit for his investigations is controlled by Mr Robinson and Mr McGuinness.
He
has stressed that if the terms were widened there would be implications
on the time frame of when the report would be completed.
Mr Connolly's call for a clerical abuse inquiry is backed by Amnesty International.
Patrick
Corrigan, Northern Ireland Programme Director, said the watchdog audit
provided another glimpse into the horror of abuse suffered by children
in parishes in both Northern Ireland and the Republic of Ireland and the
way in which figures in the Church hierarchy permitted the abuse to
continue.
He warned church-approved
reviews were no substitute for an independent investigation into
clerical child sex abuse throughout Northern Ireland.
"It
is increasingly clear that clerical child sex abuse happened in
Northern Ireland over many years and over many parishes - but only a
proper state-instituted inquiry will tell us the extent of the problem
and help bring to account those responsible," Mr Corrigan said.
"The
abuse knew no borders and, indeed as we know, in some instances, the
abusers were moved across parish and national borders, abusing children
as they went."
He stressed clerical
abuse survivors in Northern Ireland wanted an independent public inquiry
like in the Republic of Ireland, which saw Taoiseach Enda Kenny speak
out on their behalf.
"Yet, in Northern
Ireland, the Historic Institutional Abuse Inquiry specifically excludes
victims of clerical abuse who were not residents of children's homes,"
he added.
Ian Elliott, head of the National Board for Safeguarding Children, said he did not think a state inquiry was necessary.
"I'm
not a fan because they tend to be very costly, take a long period of
time and often tell you what you already know," he said.
He added: "I think what came out of Clogher today was voluntarily offered by the diocese and put in the public domain.
"Why do you need a statutory inquiry for if it you can get it another way?."
