How the Church of our Saviour, the New Jerusalem prophesied of in Scripture, was built.
Life of Constantine, with Orations · Eusebius of Caesarea
This was the emperor’s letter; and his directions were at once carried into effect. Accordingly, on the very spot which witnessed the Saviour’s sufferings, a new Jerusalem was constructed, over against the one so celebrated of old, which, since the foul stain of guilt brought on it by the murder of the Lord, had experienced the last extremity of desolation, the effect of Divine judgment on its impious people. It was opposite this city that the emperor now began to rear a monument to the Saviour’s victory over death, with rich and lavish magnificence. And it may be that this was that second and new Jerusalem spoken of in the predictions of the prophets, concerning which such abundant testimony is given in the divinely inspired records.
