XXVI Faith

The Fathers speak

Each day a few lines from the Fathers of the Church — the bishops, martyrs and teachers of the first centuries. Every passage here is one the Catechism of the Catholic Church itself quotes, so you can read it with the Church’s own explanation beside it. On a Father’s feast, his own words are chosen.

Saint Augustine of Hippo — life, feast and tomb

Our heart is restless

Great art Thou, O Lord, and greatly to be praised; great is Thy power, and of Thy wisdom there is no end. And man, being a part of Thy creation, desires to praise Thee … Thou movest us to delight in praising Thee; for Thou hast formed us for Thyself, and our hearts are restless till they find rest in Thee.

Saint Augustine of Hippo, Confessions I, 1 Cited in the Catechism of the Catholic Church, 30 · Translation: NPNF I/1

Wholly full of Thee

When I shall cleave unto Thee with all my being, then shall I in nothing have pain and labour; and my life shall be a real life, being wholly full of Thee. But now since he whom Thou fillest is the one Thou liftest up, I am a burden to myself, as not being full of Thee.

Saint Augustine of Hippo, Confessions X, 28, 39 Cited in the Catechism of the Catholic Church, 45 · Translation: NPNF I/1

We shall rest and see

God Himself, who is the Author of virtue, shall there be its reward … He shall be the end of our desires who shall be seen without end, loved without cloy, praised without weariness. … There we shall rest and see, see and love, love and praise. This is what shall be in the end without end.

Saint Augustine of Hippo, The City of God XXII, 30 Cited in the Catechism of the Catholic Church, 2550 · Translation: NPNF I/2

The word is added to the element

Why does He not say, Ye are clean through the baptism wherewith ye have been washed, but “through the word which I have spoken unto you,” save only that in the water also it is the word that cleanseth? Take away the word, and the water is neither more nor less than water. The word is added to the element, and there results the Sacrament, as if itself also a kind of visible word.

O sign of unity!

It is for this that the Apostle Paul, expounding this bread, says: “One bread,” saith he, “we being many are one body.” O mystery of piety! O sign of unity! O bond of charity! He that would live has where to live, has whence to live.

Saint Augustine of Hippo, Tractates on the Gospel of John 26, 13 Cited in the Catechism of the Catholic Church, 1398 · Translation: NPNF I/7

Desire exercised in prayer

Why this should be done by Him who “before we ask Him knoweth what things we have need of,” might perplex our minds, if we did not understand that the Lord our God requires us to ask not that thereby our wish may be intimated to Him, for to Him it cannot be unknown, but in order that by prayer there may be exercised in us by supplications that desire by which we may receive what He prepares to bestow.

Saint Irenaeus of Lyons — life, feast and tomb

The glory of God is a living man

For the glory of God is a living man; and the life of man consists in beholding God. For if the manifestation of God which is made by means of the creation, affords life to all living in the earth, much more does that revelation of the Father which comes through the Word, give life to those who see God.

A precious deposit

Saint Irenaeus of Lyons, Against Heresies III, 24, 1 Cited in the Catechism of the Catholic Church, 175 · Translation: ANF 1

In accordance with the Eucharist

But our opinion is in accordance with the Eucharist, and the Eucharist in turn establishes our opinion. For we offer to Him His own, announcing consistently the fellowship and union of the flesh and Spirit. For as the bread, which is produced from the earth, when it receives the invocation of God, is no longer common bread, but the Eucharist, consisting of two realities, earthly and heavenly; so also our bodies, when they receive the Eucharist, are no longer corruptible, having the hope of the resurrection to eternity.

As if she had but one soul

The Church, though dispersed through our the whole world, even to the ends of the earth, has received from the apostles and their disciples this faith … having received this preaching and this faith, although scattered throughout the whole world, yet, as if occupying but one house, carefully preserves it. She also believes these points [of doctrine] just as if she had but one soul, and one and the same heart, and she proclaims them, and teaches them, and hands them down, with perfect harmony, as if she possessed only one mouth.

The medicine of immortality

Stand fast, brethren, in the faith of Jesus Christ, and in His love, in His passion, and in His resurrection … breaking one and the same bread, which is the medicine of immortality, and the antidote which prevents us from dying, but a cleansing remedy driving away evil, [which causes] that we should live in God through Jesus Christ.

The Church for his mother

The spouse of Christ cannot be adulterous; she is uncorrupted and pure. She knows one home; she guards with chaste modesty the sanctity of one couch. She keeps us for God. … He can no longer have God for his Father, who has not the Church for his mother.

Saint Cyprian of Carthage, On the Unity of the Church 6 Cited in the Catechism of the Catholic Church, 181 · Translation: ANF 5

When we call God Father

We ought then, beloved brethren, to remember and to know, that when we call God Father, we ought to act as God’s children; so that in the measure in which we find pleasure in considering God as a Father, He might also be able to find pleasure in us. Let us converse as temples of God, that it may be plain that God dwells in us.

Saint Justin Martyr — life, feast and tomb

On the day called Sunday

And on the day called Sunday, all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ceased, the president verbally instructs, and exhorts to the imitation of these good things. Then we all rise together and pray, and, as we before said, when our prayer is ended, bread and wine and water are brought, and the president in like manner offers prayers and thanksgivings, according to his ability, and the people assent, saying Amen; and there is a distribution to each, and a participation of that over which thanks have been given.

Christian, acknowledge thy dignity

Christian, acknowledge thy dignity, and becoming a partner in the Divine nature, refuse to return to the old baseness by degenerate conduct. Remember the Head and the Body of which thou art a member.

We call it the Gift

We call it the Gift, the Grace, Baptism, Unction, Illumination, the Clothing of Immortality, the Laver of Regeneration, the Seal, and everything that is honourable. We call it the Gift, because it is given to us in return for nothing on our part; Grace, because it is conferred even on debtors; Baptism, because sin is buried with it in the water; Unction, as Priestly and Royal, for such were they who were anointed; Illumination, because of its splendour; Clothing, because it hides our shame; the Laver, because it washes us; the Seal because it preserves us, and is moreover the indication of Dominion.

Like a mustard seed

For the articles of the Faith were not composed as seemed good to men; but the most important points collected out of all the Scripture make up one complete teaching of the Faith. And just as the mustard seed in one small grain contains many branches, so also this Faith has embraced in few words all the knowledge of godliness in the Old and New Testaments.

Saint Ambrose — life, feast and tomb

The word of Christ changes

Let us prove that this is not what nature made, but what the blessing consecrated, and the power of blessing is greater than that of nature, because by blessing nature itself is changed. … Shall not the word of Christ, which was able to make out of nothing that which was not, be able to change things which already are into what they were not? For it is not less to give a new nature to things than to change them.

Thou hast tasted the Blood of the Lord

Thou hast tasted the Blood of the Lord, and not even thereupon dost thou acknowledge thy brother. Of what indulgence then art thou worthy? Whereas if even before this thou hadst not known him, thou oughtest to have come to the knowledge of him from the Table; but now thou dishonorest the Table itself; he having been deemed worthy to partake of it and thou not judging him worthy of thy meat.

The honour paid to the image

… and so the doxology ascribed by us is not plural but one; because the honour paid to the image passes on to the prototype. Now what in the one case the image is by reason of imitation, that in the other case the Son is by nature.
