  • N.B.1, Catholic Online rightly notes that: “The Catholic Encyclopedia is the most comprehensive resource on Catholic teaching, history, and information ever gathered in all of human history.” As the original Preface states:
    • “The Catholic Encyclopedia, as its name implies, proposes to give its readers full and authoritative information on the entire cycle of Catholic interests, action and doctrine. What the Church teaches and has taught; what she has done and is still doing for the highest welfare of mankind; her methods, past and present; her struggles, her triumphs, and the achievements of her members, not only for her own immediate benefit, but for the broadening and deepening of all true science, literature and art—all come within the scope of The Catholic Encyclopedia… It records all that Catholics have done, not only in behalf of charity and morals, but also for the intellectual and artistic development of mankind. It chronicles what Catholic artists, educators, poets, scientists and men of action have achieved in their several provinces.”
  •  N.B.2, Note that, although the original texts may be in the public domain, the online editions may be subject to copyright. Kindly observe the relevant laws when quoting or otherwise using them.

O God, our refuge and our strength, look down with mercy upon the people who cry to Thee; and by the intercession of the glorious and immaculate Virgin Mary, Mother of God, of Saint Joseph her spouse, of the blessed Apostles Peter and Paul, and of all the saints, in Thy mercy and goodness hear our prayers for the conversion of sinners, and for the liberty and exaltation of the Holy Mother the Church. Through the same Christ Our Lord. Amen. (From Sancta Missa)
