Saint John of Damascus

Being comes first, and afterwards, being good or evil. However, had God kept from being made those who through His goodness were to have existence but who by their own choice were to become evil, then evil would have prevailed over the goodness of God. Thus, all things which God makes He makes good, but each one becomes good or evil by his own choice.

-- Saint John of Damascus

Saint John Bosco

Fly from bad companions as from the bite of a poisonous snake. If you keep good companions, I can assure you that you will one day rejoice with the blessed in Heaven; whereas if you keep with those who are bad, you will become bad yourself, and you will be in danger of losing your soul. 

-- Saint John Bosco

Saint Justin Martyr

I have endeavored to learn all doctrines; but I have acquiesced at last in the true doctrines, those namely of the Christians, even though they do not please those who hold false opinions.

-- Saint Justin Martyr at his trial

Saint Vincent de Paul

It was His Will that after His death the Church should give us His image in the crucifix, that he might appear to us in a condition of utmost ignominy. And why? He did it because He knew the worth of humility and the danger of the sin which opposes it.

-- Saint Vincent de Paul

Saint Columbanus

All we Irish dwelling on the edge of the world are disciples of Saints Peter and Paul and of the disciples who, under the Holy Spirit, wrote the Sacred Canon. We accept nothing outside this evangelical and apostolic teaching. There was no heretic, no Jew, no schismatic, but the Catholic Faith, as first delivered to us by you, the successor of the apostles, is kept unshaken.... We, indeed, are, as I have said, chained to the Chair of Saint Peter; for although Rome is great and known afar, it is great and honored with us only by this Chair. 

-- Saint Columbanus

Saint Augustine of Hippo

The Kingdom of Heaven, O man, requires no other price than yourself. The value of it is yourself. Give yourself for it and you shall have it.

-- Saint Augustine of Hippo

Saint John Chrysostom

Eating and drinking don't make friendships - such friendship even robbers and murderers have. But if we are friends, if we truly care for one another, let's help one another spritually....Let's hinder those things that lead our friends away to hell.

-- Saint John Chrysostom
