A portion of the prayer has been incorporated into the liturgy of the Roman Catholic Church for use by the personal ordinariates established to bring the Anglican patrimony into the Church.  Observance of the memorial of Saint Richard of Chichester on 16 June is inscribed in the calendar of Divine Worship: The Missal and the following Collect is provided:
  MOST merciful Redeemer,
  who gavest to thy Bishop Richard a love of learning,
  a zeal for souls, and a devotion to the poor:
  grant that, encouraged by his example,
  and aided by his prayers,
  we may know thee more clearly,
  love thee more dearly,
  and follow thee more nearly,
  day by day;
  who livest and reignest with the Father
  in the unity of the Holy Spirit, ever one God,
  world without end. Amen.
