In a secular country, which we are as of 5 January 1973 when the Fifth amendment to the constitution was added removing the special position of the Catholic Church, I think that no school which receives state funding should have any religious ideology behind it. The reasons are such: being a secular country the state is not supposed to give special position to any religious denomination, with a requirement that all children to the age of 16 go to school and an obligation that the state provide that education it follows that the state should not support a system where it is impractical for parents who wish their child to get a secular (or even areligious) education. It is reasonable to suggest that a secular school would cater for more people than a Catholic school would, as it is possible (and possibly even advisable to) conduct religious education in parallel to (but outside of) a secular school education. This is a better situation for a larger set of people than that of an education with a particular ideology behind it.
