In one place, St. Leonard expounds on the number of those who make it to heaven. He is not optimistic. And he gives reasons.
Christ died that all might be saved. Not all will avail themselves of what Christ did for us. It may be, as many of the greatest spiritual writers and doctors of the Church have taught, that few are saved. Over the centuries those few might amount to “many”, but many souls may be lost. We can squander our membership in the Kingdom of God.
Here is a paragraph to whet the appetite for more of this rich fare HERE.
From a sermon on the number of those who will be saved.
I would not finish if I had to point out all the figures by which Holy Scripture confirms this truth; let us content ourselves with listening to the living oracle of Incarnate Wisdom. What did Our Lord answer the curious man in the Gospel who asked Him, “Lord, is it only a few to be saved?” Did He keep silence? Did He answer haltingly? Did He conceal His thought for fear of frightening the crowd? No. Questioned by only one, He addresses all of those present. He says to them: “You ask Me if there are only few who are saved?” Here is My answer: “Strive to enter by the narrow gate; for many, I tell you, will seek to enter and will not be able.” Who is speaking here? It is the Son of God, Eternal Truth, who on another occasion says even more clearly, “Many are called, but few are chosen.” He does not say that all are called and that out of all men, few are chosen, but that many are called; which means, as Saint Gregory explains, that out of all men, many are called to the True Faith, but out of them few are saved. Brothers, these are the words of Our Lord Jesus Christ. Are they clear? They are true.
Tell me now if it is possible for you to have faith in your heart and not tremble.
