8 Nor will less profit accrue to the state if the education of youth is wisely and rightly provided for from the beginning. Such are the times and customs that too many people with too much effort strive to keep studious youth away from the vigilance of the Church and the salutary virtue of religion. Schools called neuter, mixed, and lay are popular and sought out here and there, doubtless with the intention that the students grow up ignorant of all things holy and of all religious concerns. Since this evil is more widespread and greater than its remedies, we see a progeny growing up uninterested in spiritual goods, without religion and often impious. Keep so great a calamity out of Hungary with all your energy! The education of youth from childhood in Christian habits and Christian wisdom is today of the greatest possible concern not only to the Church, but also to the state. All who are truly wise understand this. That is why We see many Catholic men in many places who are deeply concerned about the proper upbringing of youth, devoting special and constant effort to this matter, undismayed by the greatness of the labor or by the cost. We also know of many in Hungary who are working toward the same goal with similar proposals. Permit Us nevertheless to rouse your episcopal zeal even more. - In this grave situation, We desire that in the public education of youth, that part be reserved to the Church which has been divinely assigned to it. All We can do is to exhort you to deal vigorously with this matter. Meanwhile continue to admonish fathers again and again not to permit their children to study and learn so as to threaten injury to their Catholic faith. At the same time see to it that the schools which are under your or the clergy's direction be commendable for their soundness of doctrine and the uprightness of their teachers. This is to be understood not only of primary schools, but also of those of higher learning.
