Words & Wisdom
“If you would suffer patiently the adversities and miseries of this life, be a man of prayer.”
“Truly, matters in the world are in a bad state; but if you and I begin in earnest to reform ourselves, a really good beginning will have been made.”
Treatise on Prayer and Meditation
Peter's brief masterwork on mental prayer — declared by Pope Gregory XV to have been written under the inspiration of the Holy Spirit and praised by Teresa of Ávila and Francis de Sales as among the finest guides to the interior life ever written.
O holy Peter of Alcántara, who stripped yourself of every earthly comfort to walk barefoot through the roads of Extremadura and kneel through the long nights in prayer — intercede for us before the throne of God. You who wrote that a man of prayer can endure any adversity, teach us to pray with your constancy. You who guided Teresa of Ávila in the founding of her reform, intercede for all who labor to renew the Church in our own day. You who declared that matters in the world are in a bad state, but that one person's earnest reform makes a really good beginning — give us courage to begin. Patron of Brazil, of those who keep watch through the night, and of all who carry the weight of fever and affliction — pray for us. Saint Peter of Alcántara, friend of prayer and enemy of comfort, pray for us. Amen.
