Bede

"Will the stones be rebuilt?" etc. For the stones were rebuilt, burnt from the heaps of dust, and were placed again in the work of the holy city, when those who had either denied the faith under the fire of persecutions or had lost the purity of conduct under the grips of vice, repented by the mercy of the Lord; so that they both recover the integrity of the catholic faith by steadfast profession, and obtain the ornaments of virtues by amended morals.
