St Maurus, Abbot
Os justi meditabitur sapientiam, et lingua ejus loquetur judicium: lex Dei ejus in corde ipsius. * Noli aemulari in malignantibus: neque zelaveris facientes iniquitatem.
The mouth of the just shall meditate wisdom, and his tongue shall speak judgement: the law of his God is in his heart. * Be not emulous of evildoers: nor envy them that work iniquity.
(Psalm 36:30-31 and 1 from the Introit of Mass)
Intercéssio nos, quaesumus, Dómine, beáti Mauri Abbátís comméndet: ut, quod nostris méritis non valémus, ejus patrocínio assequámur.
May the intercession of the blessed Abbot Maurus, we beseech Thee, O Lord, commend us unto Thee, that what we cannot have through our own merits, we may obtain through his patronage.
