Undertaking religious retreats

We wish to recommend heartily to all the practice of retreats. When we seclude ourselves for some days from our accustomed occupations and habitual environment, and retire into solitude and silence, we are then more attentive to give ear to the voice of God, which consequently penetrates more deeply into our soul. Retreats, while they call us to a more holy fulfillment of the duties of our ministry, and to the contemplation of the Mysteries of the Redeemer, give new strength to our will, that we may "serve Him without fear, in holiness and justice before Him all our days". (Papal Writings, Menti Nostrae, 23 September 1960).
