15 When we observe the tendency of this age as a whole, it is lamentable some Catholic men everywhere do not practice the Catholic religion as they should, either in thought or in action. It is also lamentable that men make Catholicism almost the same as the form of any other religion and, in fact, even hold the former in suspicion and hatred. It is scarcely any use to say what sort of act it is to reject with degenerate spirit this outstanding inheritance from their ancestors. Nor is it any use to note how much it is the mark of an ungrateful and uncircumspect mind, both to be unwilling to recognize the longstanding benefits of the Catholic religion, and to neglect those anticipated benefits. In Catholic wisdom and doctrine, a power and effectiveness inheres which is thoroughly wonderful and works in many ways for the good of human society. Since it does not vanish with the passage of time, it is always the same and vigorous; in the same way, it is likely to be beneficial in modern times provided it is not stifled.
