In his book The Freedom of Morality, Christos Yannaras cites the Hymn of the Nun Kassiani in his discussion of the “unsearchable immensity” in the sin of the human person and the immeasurable mercy of a personal God for the truly repentant human person. Sung in the Orthodox Church at the Bridegroom Matins and the Liturgy of the Presanctified Gifts for Great and Holy Wednesday, the Hymn of the Nun Kassiani is a profound theological statement that conveys the kenotic love of Christ for his creation in spite of its “multitude of sins.”
