Divini Illius Magistri §82

⁸² In other countries of mixed creeds, things are otherwise, and a heavy burden weighs upon Catholics, who under the guidance of their Bishops and with the indefatigable cooperation of the clergy, secular and regular, support Catholic schools for their children entirely at their own expense; to this they feel obliged in conscience, and with a generosity and constancy worthy of all praise, they are firmly determined to make adequate provision for what they openly profess as their motto: "Catholic education in Catholic schools for all the Catholic youth." If such education is not aided from public funds, as distributive justice requires, certainly it may not be opposed by any civil authority ready to recognize the rights of the family, and the irreducible claims of legitimate liberty.
