The Church as the mother and mistress of truth, urges parents to remember their duty to give to their children a good education, especially religious and moral, since the entire work of education is intimately and necessarily related to the ultimate end of life human, eternal happiness. Pope Pius XI recalls this prime importance:
In fact, since education consists essentially in preparing man for what he must be and for what he must do here below, in order to attain the sublime end for which he was created, it is clear that there can be no true education which is not wholly directed to man's last end, and that in the present order of Providence, since God has revealed Himself to us in the Person of His Only Begotten Son, Who alone is "the way, the truth and the life," there can be no ideally perfect education which is not Christian education.
From this we see the supreme importance of Christian education, not merely for each individual, but for families and for the whole of human society, whose perfection comes from the perfection of the elements that compose it.
From these same principles, the excellence, we may well call it the unsurpassed excellence, of the work of Christian education becomes manifest and clear; for after all it aims at securing the Supreme Good, that is, God, for the souls of those who are being educated, and the maximum of well-being possible here below for human society.
And this it does as efficaciously as man is capable of doing it, namely by cooperating with God in the perfecting of individuals and of society, in as much as education makes upon the soul the first, the most powerful and lasting impression for life according to the well-known saying of the Wise Man, "A young man according to his way, even when he is old, he will not depart from it." With good reason therefore did St. John Chrysostom say, "What greater work is there than training the mind and forming the habits of the young?" (Divini illius Magistri # 7, 8)
It is to this important work that the Priestly Society of St. Pius X seeks through its school work: elementary schools, high schools and colleges.
