Pope Saint Clement I

Charity unites us to God. There is nothing mean in charity, nothing arrogant. Charity knows no schism, does not rebel, does all things in concord. In charity all the elect of God have been made perfect. 

-- Pope Saint Clement I 

Saint Alphonsus Liguori

We do not fix our affections on borrowed goods, because we know that they must soon be returned to the owner. All earthly goods are lent to us: it is folly to set our heart on what we must soon quit. Death shall strip us of all. The acquisitions and fortunes of this world all terminate in a dying grasp, in a funeral, in a descent into the grave. The house which you have built for yourself you must soon give up to others. 

                         
-- Saint Alphonsus Liguori

Saint Angela Merici

He says: A good tree, that is, a good heart as well as a soul on fire with charity, can do nothing but good and holy works. For this reason Saint Augustine said: "Love, and do what you will," namely, possess love and charity and then do what you will. It is as if he had said: Charity is not able to sin. 

-- Saint Angela Merici

Saint Melito of Sardis

We have collected together extracts from the Law and the Prophets relating to those things which have Been declared concerning our Lord Jesus Christ, that we may prove to your love that this Being is perfect reason, the Word of God; He who was begotten before the light; He who is Creator together with the Father; He who is the Fashioner of man; He who is all in all; He who among the patriarchs is Patriarch; He who in the law is the Law; among the priests, Chief Priest; among kings, the Ruler; among prophets, the Prophet; among the angels, Archangel; in the voice of the preacher, the Word; among spirits, the Spirit; in the Father, the Son; in God, God; King for ever and ever.
