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

Saint Ambrose of Milan

This Creed is the spiritual seal, our heart's meditation and an ever-present guardian; it is, unquestionably, the treasure of our soul.

-- Saint Ambrose of Milan

Saint Cyril

O Lord, my God, you have created the choirs of angels and spiritual powers; you have stretched forth the heavens and established the earth, creating all that exists from nothing. You hear those who obey your will and keep your commands in holy fear. Hear my prayer and protect your faithful people, for you have established me as their unsuitable and unworthy servant. “Make your people known for the unit and profession of their faith. Inspire the hearts of your people with your word and your teaching. You called us to preach the Gospel of your Christ and to encourage them to lives and works pleasing to you. “I now return to you, your people, your gift to me. Direct them with your powerful right hand, and protect them under the shadow of your wings. May all praise and glorify your name, the Father, Son, and Holy Spirit. Amen.

-- Saint Cyril from an old Slavonic biography

Saint Josemaría Escrivá

Either we learn to find our Lord in ordinary, everyday life, or else we shall never find Him.
