I exhort you, and I will not cease to exhort you to pay heed not only to what is said here, but when you are home also you should occupy yourselves attentively with the reading of Holy Scripture. Let no one say to me such cold words-worthy of judgment---as these: ‘I am occupied with a trial, I have obligations in the city, I have a wife, I have to feed my children, and it is not my duty to read the Scripture but the duty of those who have renounced everything.’ What are you saying?! It is not your duty to read Scripture because you are distracted by innumerable cares? On the contrary, it is your duty more than those others, more than the monks; they do not have such need of help as do you who live in the midst of such cares. You need treatment all the more, because you are constantly under such blows and are wounded so often. The reading of Scripture is a great defense against sin. Ignorance of the Scripture is a great misfortune, a great abyss. Not to know anything from the word of God is a disaster. This is what has given rise to heresies, to immorality; it has turned everything upside down.
"Fasting is the change of every part of our life, because the sacrifice of the fast is not the abstinence but the distancing from sins. Therefore, whoever limits the fast to the deprivation of food, he is the one who, in reality, abhors and ridicules the fast. Are you fasting? Show me your fast with your works. Which works? If you see someone who is poor, show him mercy. If you see an enemy, reconcile with him. If you see a friend who is becoming successful, do not be jealous of him! If you see a beautiful woman on the street, pass her by."
St. John Chrysostom, On Fasting.
Mary was made Mother of God to obtain salvation for many who, on account of their wicked lives, could not be saved according to the rigor of Divine justice, but might be saved with the help of her sweet mercy and powerful intercession." St. John Chrysostom, On the Theotokos.
"Come, then, let us observe the Feast. Truly wondrous is the whole chronicle of the Nativity. For this day the ancient slavery is ended, the devil confounded, the demons take to flight, the power of death is broken, paradise is unlocked, the curse is taken away, sin is removed from us, error driven out, truth has been brought back, the speech of kindliness diffused, and spreads on every side, a heavenly way of life has been ‘in planted on the earth, angels communicate with men without fear, and men now hold speech with angels." St. John Chrysostom, On the Nativity of Christ.
"This is the Lord of glory Who is ascended into the heavens with a shout, and is seated on the right hand of the Father. Under His authority are angels, and dominions and powers, and it is He Who receives our pained prayers, and makes us victors over the pirates of this world. Under His dominion is every rank of the unclean spirits, as He says to us: 'Behold, I have given you authority to trample upon snakes and scorpions.'" St. John Chrysostom, On the Ascension.
Have you sinned? Come to Church. Tell God, ‘I have sinned.’ I do not demand anything else of you than this. Holy Scripture states, ‘Be the first one to tell of your transgressions, so you may be justified.’ Admit the sin to annul it. This requires neither labor nor a circuit of words, nor monetary expenditure, nor anything else whatsoever such as these. Say one word, think carefully about the sin and say, ‘I have sinned.'” St John Chrysostom On Sin & Repentance
