Since then the holy Church has one time of persecution, another time of peace, our Lord has noticed both times in His command to us. For at the time of persecution we must lay down our soul, that is our life, which He signified, saying, Whosoever shall lose his life. But in time of peace, those things which have the greatest power to subdue us, our earthly desires, must be vanquished; which He signified, saying, What does it profit a man, &c. Now we commonly despise all fleeting things, but still we are so checked by that feeling of shame so common to man, that we are yet unable to express in words the uprightness which we preserve in our hearts. But to this wound the Lord indeed subjoins a suitable application, saying, For whoever shall be ashamed of me and my words, of him shall the Son of man be ashamed.
