Kyriakos

Kyriakos (also rendered Cyriacus) is known only as a monk to whom Nilus of Ancyra addressed at least six letters of spiritual direction, in the milieu of early-5th-century Ancyra (modern Ankara) in Galatia. The letters treat him purely as a recipient of ascetic and exegetical counsel: Nilus expounds Pauline and scriptural passages on the resurrection body, the soul's longing to be released and to be with Christ, the Eucharist as the life-giving flesh of God, and the spiritual warfare against demonic thoughts that seat themselves upon the mind. The tone is that of a teacher instructing a monastic disciple, repeatedly warning against slackness of attentiveness and exhorting him to enlarge his soul to receive the divine communications. Beyond his role as Nilus's correspondent, he is otherwise unattested.
