Feb. 29, 433. John Cassian, Abbot at Marsailles. Holy and Mighty One, whose beloved Son Jesus Christ blessed the pure in heart: We offer thanks for the life and teachings of John Cassian that draw us to a discipline of holy living for the sake of thy reign. Call us to turn the gaze of the eyes of our soul always toward thee, that we may abide in thy love, shown to us in our Savior Jesus Christ; who with thee and the Holy Spirit is one God, living and true, to the ages of ages. Amen.
