When you are before the altar where Christ reposes, you ought no longer to think that you are amongst men; but believe that there are troops of angels and archangels standing by you, and trembling with respect before the sovereign Master of Heaven and earth. Therefore, when you are in church, be there in silence, fear, and veneration.
Saint John ChrysostomSince it is likely that, being men, they would sin every day, St. Paul consoles his hearers by saying 'renew yourselves' from day to day. This is what we do with houses: we keep constantly repairing them as they wear old. You should do the same thing to yourself. Have you sinned today? Have you made your soul old? Do not despair, do not despond, but renew your soul by repentance, and tears, and Confession, and by doing good things. And never cease doing this.
Saint John Chrysostom
