Dei Verbum , article 10.

It is clear, therefore, that sacred tradition, Sacred Scripture and the teaching authority of the Church, in accord with God's most wise design, are so linked and joined together that one cannot stand without the others, and that all together and each in its own way under the action of the one Holy Spirit contribute effectively to the salvation of souls.

Luke 1:46-55

And Mary said, "my soul magnifies the Lord, and my spirit rejoices in God my Savior, for he has regarded the low estate of his handmaiden.  For behold, henceforth all generations will call me blessed; for he who is mighty has done great things for me, and holy is his name.  And his mercy is upon those who fear him from generation to generation.  He has shown strength with his arm, he has scattered the proud in his imagination of their hearts, he has put down the mighty from their thrones, and exalted those of low degree; he has filled the hungry with good things, and rich he sent empty away.  He has helped his servant Israel, in remembrance of his mercy, as he spoke to our fathers, to Abraham and to his posterity forever."

St. Clement of Rome

Let us fix our gaze on the blood of Christ and realize how precious it is to His Father, seeing that it was poured out for our salvation and brought to grace of our conversion to the whole world.  Let us look back over all the generations, and learn from generation to generation the Lord has given an opportunity of repentance to all who would return to Him.

St. John of Damascus

It appears then, that the most proper of all the names given to God is "He That Is," as He Himself said in answer to Moses on the mountain, "Say to the sins of Israel, 'He That Is has sent me,'" (Exodus 3:14) for He keeps all being in His own embrace, like a sea of essence, infinite and unseen.

Catechism of the Catholic Church, paragraph 808

The Church is the Bride of Christ: he loved her and handed himself over for her.  He has purified her by his blood and made her the fruitful mother of all God's children.

St. Augustine

The soul is to the human body as the Holy Spirit is to the Body of Christ, which is the Church.

St. Gregory Lopez

If I were to die within a few hours, I would do nothing more than I do now.  For now I am actually giving to God all that I have.  I cannot give more unless God in his mercy bestows it on me.
