St. Hilarion the New of Dalmatia

Hilarion was born in Cappadocia in the late eighth century and entered the great Dalmatian monastery in Constantinople — one of the leading monastic houses of the city — as a young man. He rose through the offices of the community and was eventually elected its abbot, governing it for many years and becoming one of the prominent monastic figures of his day. He is called "the New" to distinguish him from the great fourth-century Hilarion of Palestine.

When the second wave of iconoclasm broke out under the Emperor Leo V the Armenian in 815, Hilarion took his place among the bishops and abbots who refused to subscribe. The Studite monks, the Patriarch Nicephorus, and the abbots of the principal Constantinopolitan monasteries stood together in this resistance. Hilarion was scourged, imprisoned in his own monastery under guard, and finally exiled — passed from place to place through Asia Minor as the imperial policy moved him from one prison to another. He endured this treatment for many years under Leo V, Michael II, and Theophilus.

After the restoration of the icons under the Empress Theodora in 843, Hilarion was permitted to return to his monastery. He died in peace there shortly afterward, around 845. His feast falls on June 6.
