Catechism of the Catholic Church 336:
From its beginning until death, human life is surrounded by [angels’] watchful care and intercession. “Beside each believer stands an angel as protector and shepherd leading him to life.” Already here on earth the Christian life shares by faith in the blessed company of angels and men united in God.
May the Guardian Angel of each one of you speak in your ear: “Sing and walk!”
(Cf. Pope Francis, to Pilgrims from Macerata to Loreto, 2015)
