Preacher’s Sketchbook:

Each week, a Dominican member of the Province of St. Joseph’s Preaching Advisory Board prepares this Preacher’s Sketchbook in anticipation of the upcoming Sunday Mass. The idea of the Preacher’s Sketchbook is to take quotations from the authority of the Church–the Pope, the Fathers of the Church, documents of the Councils, the saints–that can help spark ideas for the Sunday homily. Just as an artist’s sketchbook preserves ideas for later elaboration, so we hope the Preacher’s Sketchbook will provide some ideas for homiletical elaboration.

St. Augustine, On the Sermon on the Mount

And so we may interpret the altar spiritually, as being faith itself in the inner temple of God, whose emblem is the visible altar. For whatever offering we present to God, whether prophecy, or teaching, or prayer, or a psalm, or a hymn, and whatever other such like spiritual gift occurs to the mind, it cannot be acceptable to God, unless it be sustained by sincerity of faith, and, as it were, placed on that fixedly and immovably, so that what we utter may remain whole and uninjured. …But there ought also to be purity of intention on the part of the offerer. And therefore, when we are about to present any such offering in our heart, i.e. in the inner temple of God (“For,” as it is said, “the temple of God is holy, which temple you are;” and, “That Christ may dwell in the inner man by faith in your hearts”) if it occur to our mind that a brother has ought against us, i.e. if we have injured him in anything (for then he has something against us whereas we have something against him if he has injured us, and in that case it is not necessary to proceed to reconciliation: for you will not ask pardon of one who has done you an injury, but merely forgive him, as you desire to be forgiven by the Lord what you have committed against Him), we are therefore to proceed to reconciliation, when it has occurred to our mind that we have perhaps injured our brother in something; but this is to be done not with the bodily feet, but with the emotions of the mind, so that you are to prostrate yourself with humble disposition before your brother, to whom you have hastened in affectionate thought, in the presence of Him to whom you are about to present your offering. For thus, even if he should be present, you will be able to soften him by a mind free from dissimulation, and to recall him to goodwill by asking pardon, if first you have done this before God, going to him not with the slow movement of the body, but with the very swift impulse of love; and then coming, i.e. recalling your attention to that which you were beginning to do, you will offer your gift.

Vatican II, Lumen gentium (Dogmatic Constitution on the Church)

Those who approach the sacrament of Penance obtain pardon from the mercy of God for the offence committed against Him and are at the same time reconciled with the Church, which they have wounded by their sins, and which by charity, example, and prayer seeks their conversion. By the sacred anointing of the sick and the prayer of her priests the whole Church commends the sick to the suffering and glorified Lord, asking that He may lighten their suffering and save them; she exhorts them, moreover, to contribute to the welfare of the whole people of God by associating themselves freely with the passion and death of Christ.

Catechism of the Catholic Church

Jesus teaches that every oath involves a reference to God and that God’s presence and his truth must be honored in all speech. Discretion in calling upon God is allied with a respectful awareness of his presence, which all our assertions either witness to or mock.

Catechism of the Catholic Church

The moral life of Christians is sustained by the gifts of the Holy Spirit. These are permanent dispositions which make man docile in following the promptings of the Holy Spirit. The fruits of the Spirit are perfections that the Holy Spirit forms in us as the first fruits of eternal glory. The tradition of the Church lists twelve of them: “charity, joy, peace, patience, kindness, goodness, generosity, gentleness, faithfulness, modesty, self-control, chastity.”

Pope Benedict XVI, Jesus of Nazareth

You cannot come into God’s presence unreconciled with your brother; anticipating him in the gesture of reconciliation, going out to meet him, is the prerequisite for true worship of God. In so doing, we should keep in mind that God himself—knowing that we human beings stood against him, unreconciled—stepped out of his divinity in order to come toward us, to reconcile us. We should recall that, before giving us the Eucharist, he knelt down before his disciples and washed their dirty feet, cleansing them with his humble love.
