Uh oh jungo, the Tonester might get excommunicated by the Pope! So in theory he will have gone from failed priest to failed Catholic and not get into heaven when he gets there because of it.
Or because of all the actual shitty stuff he's done.
I can only assume Tony Abbott will be given the arse from Catholic Land(tm) on account of his being the health minister and therefore in a position to shut down abortion across the country as a result. Or maybe his arranging funding to the 'no dear, Abortion is murder and you will be killing an innocent' pregnancy "... helplines..." will absolve him?
Whatever happens I'd say if he springs for a nice steaming hot piece of Mary Toast for Pope Ratty then all will likely be forgiven.
