Though there are very many nations all over the earth, ...there are no more than two kinds of human society, which we may justly call two cities, ...one consisting of those who live according to man, the other of those who live according to God ....To the City of Man belong the enemies of God, ...so inflamed with hatred against the City of God.
Do you wish to be great? Then begin by being. Do you desire to construct a vast and lofty fabric? Think first about the foundations of humility. The higher your structure is to be, the deeper must be its foundation.
The good Christian should beware the mathematician and all those who make empty prophecies. The danger already exists that the mathematicians have made a covenant with the devil to darken the spirit and to confine man in the bonds of hell.
The Heavenly City outshines Rome beyond comparison. There, instead of victory, is truth; instead of high rank, holiness; instead of peace, felicity; instead of life, eternity.
There is no remedy so powerful against the heat of concupiscence as the remembrance of our Savior's Passion. In all my difficulties I never found anything so efficacious as the wounds of Christ: In them I sleep secure; from them I derive new life.
In no passage of the holy canonical books there can be found either divine precept or permission to take away our own life, whether for the sake of entering on the enjoyment of immortality, or of shunning, or ridding ourselves of anything whatever. Nay, the law, rightly interpreted, even prohibits suicide, where it says, 'Thou shalt not kill.' This is proved especially by the omission of the words "thy neighbor," which are inserted when false witness is forbidden.
Late have I loved Thee, O Lord; and behold, Thou wast within and I without, and there I sought Thee. Thou was with me when I was not with Thee. Thou didst call, and cry, and burst my deafness. Thou didst gleam, and glow, and dispell my blindness. Thou didst touch me, and I burned for Thy peace. For Thyself Thou hast made us, and restless our hearts until in Thee they find their ease. Late have I loved Thee, Thou Beauty ever old and ever new. Thou hast burst my bonds asunder; unto Thee will I offer up an offering of praise.
I have read in Plato and Cicero sayings that are wise and very beautiful; but I have never read in either of them: Come unto me all ye that labor and are heavy laden.
Everyone who observes himself doubting observes a truth, and about that which he observes he is certain; therefore he is certain about a truth. Everyone therefore who doubts whether truth exists has in himself a truth on which not to doubt.... Hence one who can doubt at all ought not to doubt the existence of truth.
In all trouble you should seek God. You should not set Him over against your troubles, but within them. God can only relieve your troubles if you in your anxiety cling to Him. Trouble should not really be thought of as this thing or that in particular, for our whole life on earth involves trouble; and through the troubles of our earthly pilgrimage we find God.
Do not be afraid to throw yourself on the Lord! He will not draw back and let you fall! Put your worries aside and throw yourself on him; He will welcome you and heal you.
