What follows is an excerpt from the book, Happiness in Holiness: A little guide to holiness of life for members of the Third order of Saint Francis and for other devout souls, edited by Rev. Apollinaris Baumgartner, O.M. Cap.* (who was later the first bishop of the diocese of Agaña, Guam), published in 1930, which purports to be an adaptation of Conduite intérieure pour toutes les actions de la journée, by Very Rev. Joseph of Dreux, O.M. Cap,* first published in 1667.
The following is attributed to St. Bonaventure, though without citation.
"Confess with simplicity as if you were speaking to an angel who knew all your secrets. Do not draw the veil of excuse over your actions and do not seek to diminish the gravity of your faults. Specify your sins but do not give the history of them. Do not enter into superfluous details and do not tell the sins of others. Acknowledge briefly and directly the faults you remember to have have committed since your last confession: but do not make a long series of of general statements such as: 'I have not loved God sufficiently well, etc.' 'I have not fervor enough, etc. ...' You may accuse yourself of such faults to God in prayer. In a word, let your confession be sincere, humble, and brief."
The book goes on:
"Listen with humility and gratitude to the admonitions of your confessor, being careful not to interrupt him repeatedly by saying, 'Yes, Father.' When the confessor imposes a penance upon you excite yourself to humility at the thought that it is in order to condescend to your weakness that he places such a slight burden on you.
"When you receive absolution, place yourself in spirit at the foot of the Cross of Christ and recite more with your heart than your lips, the act of contrition. The Precious Blood of our Lord is poured forth on your soul because its merits are applied to you when the priest pronounces the words of absolution.
"Leave the confessional giving thanks to God, and imploring Him to confirm in heaven, in accordance with the promise of Jesus Christ, the absolution which the priest has pronounced over you. Renew your resolve to amend your life, and make one practical resolution to which you will attend particularly until your next confession. Carry it out promptly and respond to the grace you have just received. Say your penance with devotion and ask God to accept it favorably, even though it is so small and inadequate. Offer some little sacrifice or some penance which you will perform that day in order to make up for what is wanting in your sacramental penance.
"Leave the church with the firm purpose of never again committing what you have confessed, lest falling back into the same faults you may become unworthy of God's mercy: 'Behold thou art made whole: sin no more, lest some worse thing happen to thee.' (John v. 14.)"
