Patristic Wisdom: Looking to the Eleventh Sunday after Pentecost

And He went through the cities and villages, teaching, and journeying toward Jerusalem. Then one said to Him, “Lord, are there few who are saved?” And He said to them, “Strive to enter through the narrow gate, for many, I say to you, will seek to enter and will not be able. When once the Master of the house has risen up and shut the door, and you begin to stand outside and knock at the door, saying, ‘Lord, Lord, open for us,’ and He will answer and say to you, ‘I do not know you, where you are from,’ then you will begin to say, ‘We ate and drank in Your presence, and You taught in our streets.’ But He will say, ‘I tell you I do not know you, where you are from. Depart from Me, all you workers of iniquity.’ There will be weeping and gnashing of teeth, when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, and yourselves thrust out. They will come from the east and the west, from the north and the south, and sit down in the kingdom of God. And indeed there are last who will be first, and there are first who will be last.” (Luke 13:22–30)

Let us listen therefore to the Savior’s words, which He addressed unto those who wanted to learn, whether they be few who are saved: and to whom the Savior answered, “Strive to enter in by the strait door.” Now this reply may seem perhaps, to wander from the scope of the question. For the man wanted to learn, whether they be few who are saved: but He described unto him the way whereby he might be saved himself, saying, “Strive to enter in by the strait door.” What reply then do we make to this objection?… What benefit resulted from it to the hearers? On the contrary it was a necessary and valuable thing to know in what way a man may attain to salvation. He is purposely silent therefore with respect to the useless question which had been asked Him, but proceeds to speak of what was essential, namely, of the knowledge necessary for the performance of those duties by which men can enter in at the strait and narrow door.…

Now I consider it my duty to mention why the door is narrow, through which a man goes unto life. Whosoever then would enter must of necessity first before everything else possess an upright and uncorrupted faith: and, secondly, a spotless morality, in which is no possibility of blame, according to the measure of human righteousness.… He who has attained unto this in mind and spiritual fortitude will enter easily by the strait door, and run along the narrow way.

“For wide is the door, and broad the way that brings down many to destruction.” And what are we to understand by its broadness? It means an unrestrained tendency to carnal lust; a base and pleasure loving life; luxurious feastings, and revelings and banquetings, and unresisted inclinations unto every thing which is condemned by the law, and displeasing to God: a stiff-necked mind that will not bow to the yoke of the law: a life accursed, and relaxed in all dissoluteness, thrusting from it the divine law, and utterly unmindful of the sacred commandments: wealth and the vices that spring from it, scorn and pride, and the vain imagining of transitory boastings. From all such things must those withdraw who would enter in by the strait door, and be with Christ, and keep festival with Him.
