St. Victorinus, Commentary on the Apocalypse: “‘And you have left your first love: remember whence you have fallen.’ (Apoc. 2:4-5) He who falls, falls from a height: therefore He said whence: because, even to the very last, works of love must be practised; and this is the principal commandment. Finally, unless this is done, He threatened to remove their candlestick out of its place, that is, to disperse the congregation.” (Translated by Robert Ernest Wallis. From Ante-Nicene Fathers, Vol. 7. Edited by Alexander Roberts, James Donaldson, and A. Cleveland Coxe. (Buffalo, NY: Christian Literature Publishing Co., 1886.))
