Let us resolve, first, greatly to respect the presence of our angel guardian, who is with us by night and by day, and not to allow ourselves to do anything in his presence but what is honourable and holy; secondly, to love him and to thank him often for his benefits; thirdly, to invoke him confidently in our needs and our temptations.
We ought to imitate our angel guardian, imitate at church his profound reverence in the presence of the tabernacle; in prayer, his recollection and devotion; in business, his union with God; in our temptations, his glorious combats with the devil at the cry of St. Michael: "Who is like to God?"; in the exercise of charity, his endurance of the faults and defects of our neighbour, his gentleness, his patience, his eagerness to oblige, his devotedness; lastly, in all things, his conformity to the good pleasure of God, the uprightness of his intentions, his pure and innocent life.
-- Hamon, Meditations
