The saints behind the name

Hilarion the New
March 28, Venerable, Ιλαρίων
St. Hilarion the New was abbot of the monastery of Pelekete in Asia Minor during the age of iconoclasm. A man of fasting, vigil, and deep humility, he guided his brotherhood in the monastic life and stood firm in the veneration of the holy icons when the emperors sought to abolish it.
Hilarion the Wonderworker
May 4, Venerable, Ιλαρίων ο Θαυματουργός
The synaxarion records that Venerable Hilarion lived a life of asceticism and was granted the gift of working wonders, reposing in peace. Beyond this little has been preserved.

Hilarion the New
June 6, Venerable, Ιλαρίων
St. Hilarion the New was abbot of the Dalmaton monastery in Constantinople in the ninth century. A monk of strict life and deep humility, he guided his brotherhood in the ways of prayer and obedience, and when the iconoclast emperors renewed their war on the holy icons he refused to submit, enduring imprisonment and exile for the sake of the Orthodox faith.
