Revelation 3:20, RSV-CE2

Behold, I stand at the door and knock; if any one hears my voice and opens the door, I will come to him and eat with him, and he with me.

Thomas à Kempis

Never be entirely idle: be either reading, or writing, or praying, or meditating, or endeavoring something for the public good.

Archbishop Fulton Sheen

The Sermon on the Mount is at such variance with all that our world hold dear that the world will crucify anyone who tries to live up to its values.  Because Christ preached them, He had to die.  Calvary was the price He paid for the Sermon on the Mount.  Only mediocrity survives. Those who call black black, and white white, are sentenced for intolerance. Only the grays live.

Catechism of the Catholic Church 1921

Authority is exercised legitimately if it is committed to the common good of society.  To attain this it must employ morally acceptable means.

Walter Hilton

When you attack the roots of sin, fix your thought on the God whom you desire rather than upon the sin which you hate.

St. Gregory Nazianzen

Your natural beauty suffices your husband, but if flaunted before many men like a net to catch a flock of birds, what will be the result?
You will be pleased by those whom your beauty pleases, returning glance for glance, gaze for gaze, then smiles and little words of love, guarded at first, but soon becoming familiar until you are openly behaving amorously.
Take heed, my tongue, lest I mention what follows!  But I will say this: Everything such foolish lovers say or do is an incitement to evil; one thing inevitably leads to another in these wretched flirtations as one piece of iron, drawn by a magnet, draws another in its turn.

St. Josemaria Escriva

You're not humble when you humble yourself, but when you are humbled by others and bear it for Christ.

St. Thomas More

I die the king's good servant, but God's first.

St. Basil

Anger is a kind of temporary madness.

Blessed Theresa of Calcutta

GOd does not create poverty. We do, because we do not share.

G. K. Chesterton

The reformer is always right about what is wrong.  He is generally wrong about what is right.

Pope Leo XIII

The chief and most excellent rule for the right use of money is one which the Christian philosophers hinted at, but which the Church has traced out clearly, and has not only made known to men's minds, but has impressed upon their lives.  It rests upon the principle that it is one thing to have a right to possession of money, and nother to have the right to use money as one wills.

G. K. Chesterton

The dipsomaniac and the abstainer both make the same mistake.  They both regard wine as a drug and not as a drink.

Pope Paul III (1534-1549)

By our Apostolic authority we define and proclaim that Indians, or any peoples who may hereafter be discovered by Catholics, although they be not Christian, must in no way be deprived of their liberty or their possessions.

St. Cyril of Jerusalem

If any man receive not Baptism, he has not salvation; except only the Martyrs, who even without the water receive the kingdom.

St. Athanasius

We do not worship a creature. Far be the thought!  For such an error belongs to heathens and Arians.  But we worship the Lord of Creation, Incarnate, the Word of God.  For if the flesh also is in itself a part of the created world, yet it has become God's body.  And we neither divide the body, being such, from the word, and worship it by itself, nor when we wish to worship the Word do we set Him far apart from the Flesh, but knowing, as we said above, that "the Word was made flesh" we recognize Him as God also, after having come in the flesh.  Who, accordingly, is so senseless to say to  the Lord: "Leave the Body that I may worship Thee".

Gaudium et Spes, 65

Growth is not to be left to a kind of mechanical course of the economic activity of individuals, nor to the authority of the government.  For this reason, doctrines which obstruct the necessary reforms under the guise of false liberty, and those which subordinate the basic rights of individual persons and groups to the collective organization of production must be shown to be erroneous.

Pope Pius XII

The faithful, more precisely the lay faithful, find themselves on the front lines of the Church's life, for  them the Church is the animating principle for human society.  Therefore, they in particular ought to have an ever clearer consciousness not only of belonging to the church, but being the Church; that is to say, the community of the faithful on earth under the leadership of the Pope, the head of all, and of the bishops in communion with him.  These are the Church.
