329–373 · Athanasius of Alexandria, Festal Letters 13.6
Now what does this mean, my beloved, but that we also, when the enemies are arrayed against us, should glory in afflictions, and that when we are persecuted, we should not be discouraged, but should the rather press after the crown of the high calling in Christ Jesus our Lord? and that being insulted, we should not be disturbed, but should give our cheek to the smiter, and bow the shoulder? For the lovers of pleasure and the lovers of enmity are tried, as saith the blessed Apostle James, ‘when they are drawn away by their own lusts and enticed.’ But let us, knowing that we suffer for the truth, and that those who deny the Lord smite and persecute us, ‘count it all joy, my brethren,’ according to the words of James, ‘when we fall into trials of various temptations, knowing that the trial of our faith worketh patience.’ Let us rejoice as we keep the feast, my brethren, knowing that our salvation is ordered in the time of affliction.
