"But let not your fasts be with the hypocrites; (Matthew 6:16) for they fast on the second and fifth day of the week; but fast on the fourth day and the Preparation (Friday). Neither pray as the hypocrites; but as the Lord commanded in His Gospel, thus pray: Our Father who art in heaven, hallowed be Your name. Your kingdom come. Your will be done, as in heaven, so on earth. Give us today our daily (needful) bread, and forgive us our debt as we also forgive our debtors. And bring us not into temptation, but deliver us from the evil one (or, evil); for Yours is the power and the glory forever. Thrice in the day thus pray."

The Didache, Chapter 8. Concerning Fasting and Prayer (the Lord's Prayer) [circa 70 AD]

"Fasting is of great benefit to the Christian soul. It humbles the body and with the humiliation of the body, the soul, too, is humbled; but although the body has been reduced to submission, the soul nevertheless suffers its own passions. Now if to the flame of the soul is added the flame of the body, who is able to endure such twofold burning? Prayer frequently extinguishes the fire of the soul, and likewise does trust in the Lord."

St. Jerome, Homily on the Psalms: Homily 33 on Psalm 106

"For the saint, every day is the day of Christ’s Resurrection, and he always feeds on the Lord’s flesh. But days for fasting and gathering together for worship were instituted by prudent men for the sake of those who leave more time for the world than for God, and are unable, or rather unwilling, to congregate in church every moment of their lives, or to put the offering of the sacrifice of their prayers to God ahead of their human activities. For how few people are there who always observe at least these few regulations about the times of prayer or fasting? Thus, we are allowed to fast always, to pray always, and to celebrate unceasingly and joyfully in the Lord’s day by receiving his body."

St. Jerome, Commentary on Galatians 4:10-11: "You observe days, and months, and seasons, and years! I am afraid I have labored over you in vain."

"By fasting of the body we are prepared for spiritual feasting."

St. Jerome, Commentary on Matthew 9:15

"I speak the sober truth when I affirm that, for the wrecks of families in our country, woman has a large share of the responsibility. In so many instances she seems to have entirely forgotten, or purposely avoided, the place she is called upon to fill. She looks to material greatness in man as her guiding star. She wishes to do what men have done, and are doing. She enters this field, foreign to all her faculties and her strength, and seems to think she is living up to a higher standard than was ever before permitted to her kind. But if she stopped a moment to consider, could she find a mission more exalted, more noble or more influential than Christian wifehood and motherhood? That makes her the helpmate of her husband, and the guide and teacher of her sons and daughters, rather than a stumbling-block in the way of all."

Cardinal James Gibbons, The Restless Woman

"God maintained the order of each sex by dividing the business of human life into two parts and assigned the more necessary and beneficial aspects to the man and the less important, inferior matters to the woman."

St. John Chrysostom, Quales Ducendae Sint Uxores [The Kind of Women Who Ought to Be Taken as Wives]

"One of the most evil and strongest influences that is felt here, perhaps the strongest and the most evil, is that of the Jews."

Pope Pius XI, 1919 Report to Cardinal Gasparri

"After creating man, God created woman and determined her mission, namely, that of being man's companion, helpmeet and consolation... It is a mistake, therefore, to maintain that woman's rights are the same as man's. Women in war or parliament are outside their proper sphere and their position there would be the desperation and ruin of society. Woman, created as man's companion, must so remain under the power of love and affection, but always under his power. How mistaken, therefore, is that misguided feminism which seeks to correct God's work. It is like a mechanic trying to correct the signs and movements of the universe. Scripture, and especially the three epistles of St. Paul, emphasizes woman's dependence on man, her love and assistance, but not her slavery to him."

Pope St. Pius X, 1909 Address to a Delegation of the Union of Italian Catholic Women

"Many Englishmen, and I am one of them, do think that the international and largely secret power of the great Jewish houses is a problem and a peril."

GK Chesterton, To the Editor of The Nation, "The Jews in Modern Life"

"Just as the Lord has His chosen saints, so does the Devil have his elect. Think of the chief heretics and you will have no doubt about his chosen band."

St. Jerome, Homilies on the Psalms, Homily 51, Psalm 140

"The devil is the hunter, eager to lure our souls into perdition."

St. Jerome, Homilies on the Psalms, Homily 20, Psalm 90

"They used to say of one elder that he implored God to [let him] see the demons and it was revealed to him: “You do not need to see them.” But he begged God: “Lord, You are able to protect me by Your hand”, whereupon God opened his eyes and he saw them and how they swarm about a man like bees, gnashing their teeth against him; but the angel of the Lord was rebuking them."

The Anonymous Sayings of the Desert Fathers, pg. 241

"It is not permitted to the Soldier of Christ that he quit the battlefield, because only death puts an end to his military service."

Pope Ven. Pius XII, Sertum Laetitiae, 16

"I perceive that nothing more saps the citadel of manly strength, whether of mind or body, than female blandishments and familiarities."

St. Augustine, Soliloquies, Book I, 17
