About Adeodatus II
Pope Adeodatus II
Pope Adeodatus II, sometimes known as Deodatus, was the bishop of Rome from 672 until his death on June 17, 676. Born in Rome around 621 AD, he was the son of Jovinianus and became a Benedictine monk at the monastery of Sant'Erasmo al Celio.
Pontificate and Actions
Adeodatus II's papacy is characterized by its relative obscurity, but it was marked by significant efforts in church improvement and theological contention. He devoted considerable energy to restoring churches in disrepair and enhancing monastic discipline. A key aspect of his pontificate was his strong opposition to Monothelitism, a Christological doctrine that was supported by the Eastern Roman emperors. In a significant move, Adeodatus II rejected the synodical letters sent to him by Patriarch Constantine I of Constantinople, a decision that resulted in his name being excluded from the diptychs in Constantinople.
During his reign, he granted Venice the right to elect its own doge. Notable construction projects included the Basilica of St. Peter at the eighth milestone of the Via Portuensis and the reconstruction of St. Erasmus. He also protected the Abbey of St. Peter and St. Paul and exempted Marmoutier Abbey in Tours from the authority of the Holy See.
Legacy
While Adeodatus II is sometimes referred to as a saint and June 26 is cited as his feast day, this status is disputed, and he does not appear in the latest official edition of the Roman Martyrology. His papacy did not seem to make outstanding contributions to civil society but was focused on ecclesiastical matters and theological defense. He died in 676 and was succeeded by Donus.
