"..if its all down to free will and conscience, is it ok took to be a practising homosexual, have an abortion, or be a priest? No, thought not."
-- Well actually, yes of course it is. All of what you mentioned is legal (in the UK anyway) You are free to do what you want and believe what you want, even in Ireland, (with the exception of abortion, I know). Who is going to stop you? How will you be stopped? Of course your own actions are always a matter of your own individual conscience, whether you're a Catholic or not. Everybody is guided in everything they choose to do by their own beliefs or value system. There is no ton of bricks hovering over the head of a Catholic, waiting to drop on you if you put a foot 'wrong'. If you decide that you have done something that doesn't square with your conscience, the Catholic Church offers the sacrament of reconciliation and you are free to avail of that too.
By the sound of your MIL, she was raised in the very old style 'learn it all off and don't ask questions' type of Catholicism in Ireland. People like her are very hard to deal with, I'll grant you that much. They are very different from younger Catholics.
"The Catholic church took children off their parents for the most spurious of reasons ( illegitimacy for example), threw them in children's homes ( often to work like slaves, as per the Goldenbridge rosary bead factory), starved them, beat them, and raped them. This went on for decades. And then when it started to come out, the Catholic heirarchy did their damnedest to cover up the whole thing. Oh, and they went running to the Irish government and got them to agree to pay most of the reparations. So it wasn't just a case of a few abusers going on to abuse, not by a long chalk."
The 'care' of children who were removed from their parents (yes, for really, really terrible reasons) was in most cases contracted out to the Catholic Church in Ireland by the Irish Government industrial schools and orphanages were farmed out to the church by the state. Hence the state's role in reparations. I personally do not believe the church was challenged enough or made to pay enough initially, but the Murphy Report was a correct move in the direction of holding the church more directly accountable for the horrors that were visited upon defenceless children for so long. I think Cardinal Brady should have resigned long ago and I believe that saying he was following orders when he colluded in the silencing of two children () smacks of the Nuremberg trial.
DP, nowhere in any of the Catholic Church's writings on the subject is homosexuality described as a 'lifestyle choice'.
I agree with Custardo regarding paedophilia probably not being linked to celibacy. It's more a question of the personality types and psychological profiles considered acceptable for admission to the seminary and passed through as priests.
