36 As regards the departure to Babylon, where the Spirit of God by the prophet Jeremiah enjoins them to go, telling them to pray for the people in whose land they dwell as strangers, because in their peace they would find peace, and to build houses, and plant vineyards and gardens—the figurative meaning is plain, when we consider that the true Israelites, in whom is no guile, passed over in the ministry of the apostles with the ordinances of the gospel into the kingdom of the Gentiles.
So the apostle, like an echo of Jeremiah, says to us, "I will first of all that prayer, supplications, intercessions and giving of thanks be made for all men, and for those in authority, that we may live a quiet and peaceable life in all godliness and charity; for this is good and acceptable in the sight of God our Saviour, who will have all men to be saved, and to come to the knowledge of the truth." Accordingly the basilicas of Christian congregations have been built by believers as abodes of peace, and vineyards of the faithful have been renewed, and gardens planted, where chief among the plants is the mustard tree, in whose wide-spreading branches the pride of the Gentiles, like the birds of heaven, in its soaring ambition, takes shelter.
Again, in the return from captivity after seventy years, according to Jeremiah's prophecy, and in the restoration of the temple, every believer in Christ must see a figure of our return as the Church of God from the exile of this world to the heavenly Jerusalem, after the seven days of time have fulfilled their course. Joshua the high priest, after the captivity, who rebuilt the temple, was a figure of Jesus Christ, the true High Priest of our restoration. The prophet Zechariah saw this Joshua in a filthy garment; and after the devil who stood by to accuse him was defeated, the filthy garment was taken from him, and a dress of honor and glory given him.
So the body of Jesus Christ, which is the Church, when the adversary is conquered in the judgment at the end of the world, will pass from the pains of exile to the glory of everlasting safety. This is the song of the Psalmist at the dedication of his house: "You have turned for me my mourning into gladness; You have removed my sackcloth, and girded me with gladness, that my glory may sing praise unto You, and not be silent."
