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

Saint Thomas More

I shall remember how Saint Peter at a blast of wind began to sink because of his lack of faith, and I shall do as he did: call upon Christ and pray to him for help. And then I trust he shall place his holy hand on me and in the stormy seas hold me up from drowning. 

-- Saint Thomas More
