Jericho as an image of the world

This was a recent reading in the Liturgy of the Hours and it blew my mind.

The capture of Jericho

Once Jericho was surrounded it had to be stormed. How then was Jericho stormed? No sword was drawn against it, no battering ram was aimed at it, no javelins were hurled. The priest merely sounded their trumpets, and the walls of Jericho collapsed.

In the Scriptures Jericho is often represented as an image of the world. There can be not doubt that the man whom the Gospel describes as going down from Jerusalem to Jericho and falling into the hands of brigands is an image of Adam being driven out of paradise into the exile of this world. Likewise the blind men in Jericho, to whom Jesus came to give sight, signified the people in this world who were blinded by ignorance, to whom the son of God came.

Jericho will fall, then; this world will perish. Indeed in the sacred books the end of the world was proclaimed long ago. How will the world be brought to an end, and by what means will it be destroyed? The answer of Scripture is: By the sound of trumpets. If you ask what trumpets, then let Paul reveal the secret. Listen to what he says: The trumpet will sound, and the dead who are in Christ will rise incorruptible. The voice of the archangel and the trumpets of God will give the signal, and the Lord himself will come down from heaven. Then the Lord Jesus will conquer Jericho with trumpets and destroy it, saving only the harlot and her household.

Jesus our Lord will come says Paul, and he will come with the sound of trumpets. He will save only the woman who received his spies, that is, his apostles, in faith and obedience, and hid them on the roof of her house; and he will join this harlot to the house of Israel. But let us not bring up her past sins again or impute them to her. She was a harlot once, but now she is joined to Christ, chaste virgin to one chaste husband. Listen to what the Apostle says of her: He has determined to present you to Christ as a chaste virgin to her one and only husband. Indeed, Paul himself had been born of her: Misled by our folly and disbelief, he said, we too were once slaves to our passions and to pleasures of every kind.

If you wish to learn more fully about how this harlot ceased to be a harlot then listen to Paul once again: And such were you also, but you have been cleansed and made holy in the name of our Lord Jesus Christ and in the Spirit of our God. To assure her escape when Jericho was destroyed, the harlot was given that most effective symbol of salvation, the scarlet cord. For it is by the blood of Christ that the entire Church is saved, in the same Jesus Christ our Lord, to whom belongs glory and dominion for ever and ever. Amen.
