St. Aloysius Gonzaga, Confessor
At the age of twenty-two (1591), wearing his innocence like a nuptial robe, on which shone the pearls of his continual tears, he died a victim to his devotion to the plague-stricken and ascended the holy mountain to take part in the heavenly banquet to which God invites the pure of heart (Secret, Offertory, Gradual).
Let us have recourse to the merits and intercession of St. Aloysius.
Benedict XIII gave him as a pattern to young people, in order that, not having always imitated him in his innocence, they may at least imitate him by doing penance (Collect).
Minuisti eum paulo minus ab Angelis: gloria et honore coronasti eum. * Laudate Dominum, omnes Angela ejus: laudate eum, omnes virtutes ejus.
Thou hast made him a little less than the angels: Thou hast crowned him with glory and honour. * Praise ye the Lord, all His angels: praise ye Him, all His hosts.
(Psalm 8:6 and Psalm 148:2 from the introit of Mass)
Caelestium donorum distributor, Deus, qui in angelico juvene Aloisio miram vitae innocentiam pari cum poenitentia sociasti: ejus meritis et precibus concede; ut, innocentem non secuti, poenitentem imitemur.
O God, who, in distributing Thy heavenly gifts, didst in the angelic youth Aloysius, unite wonderful innocence of life with an equal spirit of penance: grant through his merits and prayers, that we who have not followed him in his innocence, may imitate him in his penance.
