He was born in 1698 in Adrianople, then part of the Ottoman Empire (now Edirne, Turkey) to a well off merchant father.
He graduated from the Academy of Ioannis Zygomalas.
He then became a monk in Iviron Monastery of Mount Athos.
He became a deacon in 1713 and a presbyter in 1719.
In 1725 he was ordained archimandrite, and in particular he was named by the Ecumenical Patriarchate as Grand Archimandrite, Grand Ecclesiarch of Mount Athos, and Bishop of Polyani and Kilkis.

In 1731 he travelled to Germany and then to Russia as an envoy of the Patriarchate.
During his trips to Europe he visited Menorca, where he also served as a teacher and a pastor.
All in all, Theoklitos came in contact with social, political, diplomatic and religious practices throughout Europe.
He was concerned about the political implications of the Reformation and studied the problems that concerned the Greek diaspora.

He then attempted to mobilize the enslaved Greeks by verifying old prophecies of the Byzantine Empire.
He wrote Agathangelos (el), a well known prophetic work which was published, with minor variations, widely in Greece, either as a brochure (by Rigas Feraios) or as a book in Athens and Ermoupoli (1837-38).
He dates the oracles back to the 13th century (1279), with the original author of the work being monk Ieronymus Agathagelus from Messina of Sicily.
The latter narrates, through oracles, events of the following centuries, which the original author knows.
As a result, it fascinates the popular masses, who are becoming more optimistic about their liberation.
Thus, the supposed Latin translator of the prophetic work, Theocletus, remains under the shadow of Agathagelus.

He stayed in Dresden (1741) and shortly afterwards settled, after an invitation of the inhabitants, in neighboring Leipzig, where he founded the first Orthodox chapel (then of the Holy Trinity, now of St. George).
He died in 1759 in Leipzig.
