Saint Ambrose

No one is good but God alone. What is good is therefore divine, what is divine is therefore good.

Let there be a door to thy mouth, that it may be shut when need arises, and let it be carefully barred, that none may rouse thy voice to anger, and thou pay back abuse with abuse.

Let us take refuge from this world. You can do this in spirit, even if you are kept here in the body. You can at the same time be here and present to the Lord. Your soul must hold fast to him, you must follow after him in your thoughts, you must tread his ways by faith, not in outward show.

Nothing escapes God's knowledge. This is proved by the witness of the Scriptures and the analogy of the sun, which, although created, yet by its light or heat enters into all things.

There is nothing evil save that which perverts the mind and shackles the conscience.

God created the universe in such a manner that all in common might derive their food from it, and that the Earth should also be a property common to all.

God, who preferred the correction rather than the death of a sinner, did not desire that a homicide be punished by the exaction of another act of homicide.

God is not accustomed to refusing a good gift to those who ask for one. Since he is good, and especially to those who are faithful to him, let us hold fast to him with all our soul, our heart, our strength, and so enjoy his light and see his glory and possess the grace of supernatural joy.

A good youth ought to have a fear of God, to be subject to his parents, to give honor to his elders, to preserve his purity; he ought not to despise humility, but should love forbearance and modesty. All these are an ornament to youthful years.
