Psalms 48:13

The psalmist exhorts the people, "Behold this city." … Understand something from … its structure, its beauty, its fame, so as to learn from this God's power, how he made the lost city more mighty, and recount to your progeny God's power and the enduring course of his providence; his care of us, his leadership and shepherding last forever. Stories of this to those who come after will, in fact, prove an occasion for great advance in wisdom, a basis for more precise knowledge of God and a study of virtue.

Each generation has to pass on to the next what we have received from the former so that the saving message may pass to all generations, and all people know that he is our God and Lord, good shepherd, everlasting. Since he said, "take its buildings one by one," and entrusted to them the task of shepherding, of necessity he taught that there is one good shepherd, who laid down his life for the sheep, shepherding forever, and shepherding not only the sheep but also those called pastors of the sheep.

"Set your hearts upon her might." Not that ye may have the form of godliness, deny the power thereof, but, "upon her might set your hearts. Speak ye in her towers." What is the might of this city? Whoso would understand the might of this city, let him understand the force of love. That is a virtue which none conquereth. Love's flame no waves of the world, no streams of temptation, extinguish. Of this it is said, "Love is strong as death." For as when death cometh, it cannot be resisted; by whatever arts, whatever medicines, you meet it; the violence of death can none avoid who is born mortal; so against the violence of love can the world do nothing. For from the contrary the similitude is made of death; for as death is most violent to take away, so love is most violent to save. Through love many have died to the world, to live to God; by this love inflamed, the martyrs, not pretenders, not puffed up by vain-glory, not such as they of whom it is written, "Though I give my body to be burned, and have not charity, it profiteth me nothing," but men whom truly a love of Christ and of the truth led on to this passion; what to them were the temptations of the tormentors? Greater violence had the eyes of their weeping friends, than the persecutions of enemies. For how many were held by their children, that they might not suffer? to how many did their wives fall upon their knees, that they might not be left widows? How many have their parents forbidden to die; as we know and read in the Passion of the Blessed Perpetua! All this was done; but tears, however great, and with whatever force flowing, when did they extinguish the ardour of love? This is the might of Sion, to whom elsewhere it is said, "Peace be within thy walls, and prosperity within thy palaces."
