Saint Polycarp of Smyrna

Stand fast, therefore, in this conduct and follow the example of the Lord, 'firm and unchangeable in faith lovers of the brotherhood, loving each other, united in truth, ' helping each other with the mildness of the Lord, despising no man. 

-- Saint Polycarp of Smyrna

Saint Peter the Apostle

You are the Messiah, the Son of the living God.

Saint Peter Damian

Let us faithfully transmit to posterity the example of virtue which we have received from our forefathers.

 -- Saint Peter Damian 

Saint Thomas Becket

The harvest is good and one reaper or even several would not suffice to gather all of it into the granary of the Lord. Yet the Roman Church remains the head of all the churches and the source of Catholic teaching. Of this there can be no doubt. Everyone knows that the keys of the kingdom of heaven were given to Peter. Upon his faith and teaching the whole fabric of the Church will continue to be built until we all reach full maturity in Christ and attain to unity in faith and knowledge of the Son of God. 

-- Saint Thomas Becket

Saint Irenaeus of Lyons

If one carefully reads the Scriptures, he will find there the word on the subject of Christ -- de Christo sermonem -- and the prefiguration of the new calling. He is indeed the hidden treasure in the field -- the field in fact is the world -- but in truth, the hidden treasure in the Scriptures is Christ. Because he is designed by types and words that humanly are not possible to understand before the accomplishment of all things, that is, Christ's parousia (coming).

-- Saint Irenaeus of Lyons

Saint Bernadette of Lourdes

You must receive God well; give Him a loving welcome, for then He has to pay us rent. 

-- Saint Bernadette of Lourdes

Saint Augustine of Hippo

God does not command impossibilities, but by commanding admonishes you do what you can and to pray for what you cannot, and aids you that you may be able. 

-- Saint Augustine of Hippo
