St. Leonard of Port Maurice's sermon "On the Little Number of Those Who are Saved":
"Brothers, you must know that the most ancient belief is the Law of God, and that we all bear it written in our hearts; that it can be learned without any teacher, and that it suffices to have the light of reason in order to know all the precepts of that Law. That is why even the barbarians hid when they committed sin, because they knew they were doing wrong; and they are damned for not having observed the natural law written in their heart: for had they observed it, God would have made a miracle rather than let them be damned; He would have sent them someone to teach them and would have given them other aids, of which they made themselves unworthy by not living in conformity with the inspirations of their own conscience, which never failed to warn them of the good they should do and the evil they should avoid. So it is their conscience that accused them at the Tribunal of God, and it tells them constantly in hell, "Thy damnation comes from thee." They do not know what to answer and are obliged to confess that they are deserving of their fate.
Now if these infidels have no excuse, will there be any for a Catholic who had so many sacraments, so many sermons, so many aids at his disposal? How will he dare to say, "If God was going to damn me, then why did He create me?" How will he dare to speak in this manner, when God gives him so many aids to be saved? So let us finish confounding him.
You who are suffering in the abyss, answer me! Are there any Catholics among you? "There certainly are!" How many? Let one of them come here! "That is impossible, they are too far down, and to have them come up would turn all of hell upside down; it would be easier to stop one of them as he is falling in." So then, I am speaking to you who live in the habit of mortal sin, in hatred, in the mire of the vice of impurity, and who are getting closer to hell each day. Stop, and turn around; it is Jesus who calls you and who, with His wounds, as with so many eloquent voices, cries to you, "My son, if you are damned, you have only yourself to blame: Thy damnation comes from thee.' Lift up your eyes and see all the graces with which I have enriched you to insure your eternal salvation. I could have had you born in a forest in Barbary; that is what I did to many others, but I had you born in the Catholic Faith; I had you raised by such a good father, such an excellent mother, with the purest instructions and teachings. If you are damned in spite of that, whose fault will it be? Your own, My son, your own: "Thy damnation comes from thee.'
