The Enchiridion, Manual, or Handbook of Augustine of Hippo is alternatively titled, Faith, Hope, and Love. The Enchiridion is a compact treatise on Christian piety, written in response to a request by an otherwise unknown person, named Laurentius, shortly after the death of Saint Jerome in 420. It is intended as a model for Christian instruction or catechesis.As the title indicates, the work is organized according to the three graces necessary for the Christian worship of God: Faith, Hope and Love. Under Faith, Augustine explains the use of the Apostles' Creed, in teaching Christian doctrine and in refuting heresies. Under Hope, he briefly explains the Lord's Prayer as a model of Christian prayer. The final part is a discourse on Christian love.
