Luke 19:41

All the blessings which Jesus pronounced in His Gospel He confirms by His own example, as having declared, Blessed are the meek; He afterwards sanctions it by saying, Learn of me, for I am meek; and because He had said, Blessed are they that weep, He Himself also wept over the city. I do not deny then that the former Jerusalem was destroyed because of the wickedness of its inhabitants, but I ask whether the weeping might not perhaps concern this your spiritual Jerusalem. For if a man has sinned after receiving the mysteries of truth, he will be wept over. Moreover, no Gentile is wept over, but he only who was of Jerusalem, and has ceased to be.

For Christ had compassion upon the Jews, who wills that all men should be saved. Which had not been plain to us, were it not revealed by a certain mark of His humanity. For tears poured forth are the tokens of sorrow.

(Hom. 39. in Ev.) The merciful Redeemer wept then over the fall of the false city, which that city itself knew not was about to come upon it. As it is added, saying, If thou hadst known, even thou (we may here understand) wouldest weep. Thou who now rejoicest, for thou knowest not what is at hand. It follows, at least in this thy day. For when she gave herself up to carnal pleasures, she had the things which in her day might be her peace. But why she had present goods for her peace, is explained by what follows, But now they are hidden from thy eyes. For if the eyes of her heart had not been hidden from the future evils which were hanging over her, she would not have been joyful in the prosperity of the present. Therefore He shortly added the punishment which was near at hand, saying, For the days shall come upon thee.

(Hom. 39. in Ev.) For our Redeemer does not cease to weep through His elect whenever he perceives any to have departed from a good life to follow evil ways. Who if they had known their own damnation, hanging over them, would together with the elect shed tears over themselves. But the corrupt soul here has its day, rejoicing in the passing time; to whom things present are its peace, seeing that it takes delight in that which is temporal. It shuns the foresight of the future which may disturb its present mirth; and hence it follows, But now are they hid from thine eyes.
