Apringius of Beja, on Rev 21:21

“And the twelve gates are twelve pearls, one to each: and every several gate was of one several pearl. And the street of the city was pure gold, as it were transparent glass.”

“These words reveal the difference of merit that exists within the very beatitude of the saints. For above it was said that the entirety of the city was like pure gold, clear as glass. [Now it says that] "the streets of the city are pure gold, transparent as glass." These are the saints of the city that are of lesser merit. Nonetheless, gathered together into one congregation, it is indicated that they do not shine with a lesser light.”
