38 History bears witness how, particularly in modern times, the State has violated and does violate rights conferred by God on the family. At the same time it shows magnificently how the Church has ever protected and defended these rights, a fact proved by the special confidence which parents have in Catholic schools. As We pointed out recently in Our letter to the Cardinal Secretary of State: The family has instinctively understood this to be so, and from the earliest days of Christianity down to our own times, fathers and mothers, even those of little or no faith, have been sending or bringing their children in millions to places of education under the direction of the Church.
