Festum sanctae Bonaventurae S.R.E. Cardinalis et doctoris ecclesiae

Happy feast of St. Bonaventure, whether you keep the old calendar (in which case the feast is today) or the new (tomorrow, July 15)!

Here's the secret:

Sancti Bonaventurae Confessoris tui atque Pontificis, quaesumus, Domine, annua solemnitas pietati tuae nos reddat acceptos: ut, per haec piae placationis officia, et ill beata retributio comitetur, et nobis gratiae tuae dona conciliet. Per Dominum...

Translation from p. 1315 of the Saint Andrew Daily Missal:

May the yearly festival of saint Bonaventure Thy confessor and bishop, we beseech Thee, O Lord, render us acceptable unto Thy loving kindness; that by means of this office of holy reconciliation, a blessed reward may be rendered to him, and to us the gifts of Thy grace. Through our Lord...

And here's a bit from his Sermones Dominicales, sermo 33, dominica vi post pentecosten (that would be last sunday), ed. G. Bougerol, p.366.

Non enim potest idem homo esse iustus et peccator, bonus et malus, servus Dei et servus diaboli, quia nemo potest duobus dominis, contraria iubentibus, servire. Unde sicut navis existens in aquis plena foraminibus, si eius omnia foramina obturentur praeter unum, nihilominus propter illud unum submergetur in profundum maris; sic peccator, si omnia peccata confiteatur et unum retineat, per illud solum damnabitur.

Translation: For the same man cannot be just and a sinner, good and evil, a servant of God and a servant of the devil, because no one can serve two masters with contrary commands. Whence just as a ship existing in water full of holes, if all its holes be repared except one, still because of that one it will sink into the depths of the see; so a sinner, if all his sins be confessed and one held back, through that one alone will be damned.
