Some in the Catholic church understand better than others that the fight to preserve their separate schools will be tough and complicated.
Here is a segment from an address by Bishop Donal McKeown to the Irish Council of Churches in Swords last week.
It acknowledges that if Catholic schools are to survive they have to offer something different from what the state offers.
It rebukes those who think that Catholic schools in Northern Ireland are for the preservation of Gaelic culture.
It intimates that those schools who insist on selection procedures that privilege the middle class are already in breach of the Catholic ethos.
It says that Catholic schools must contribute to reconciliation in society.
And it recognises that there is now a more secularised generation of head teachers.
