"He passed over his fall, and appointed him first of the Apostles; wherefore He said: ' 'Simon, Simon,' etc. (in Ps. cxxix. 2). God allowed him to fall, because He meant to make him ruler over the whole world, that, remembering his own fall, he might forgive those who should slip in the future. And that what I have said is no guess, listen to Christ Himself saying: 'Simon, Simon, etc.'"
Saint John ChrysostomLet us always guard our tongue; not that it should always be silent, but that it should speak at the proper time.
Saint John ChrysostomGod does not forsake you. It is because he wishes to increase your glory that oftentimes he permits you to fall sick. Keep up your courage so that you may also hear him say: Do you think I have dealt with you otherwise than that you may be shown to be just?
Saint John Chrysostom
