Reading from the Synaxarion:
This divine Father, who was from Asia Minor, was from childhood reared
in the royal court of Constantinople, where he was instructed in
both religious and secular wisdom. Later, while still a youth, he left
the imperial court and struggled in asceticism on Mount Athos, and in
the Skete at Beroea. He spent some time in Thessalonica being treated
for an illness that came from his harsh manner of life. He was
present in Constantinople at the Council that was convened in 1341
against Barlaam of Calabria, and at the Council of 1347 against
Acindynus, who was of like mind with Barlaam; Barlaam and Acindynus claimed
that the grace of God is created. At both these Councils, the Saint
contended courageously for the true dogmas of the Church of Christ,
teaching in particular that divine grace is not created, but is the
uncreated energies of God which are poured forth throughout creation:
otherwise it would be impossible, if grace were created, for man to have
genuine communion with the uncreated God. In 1347 he was appointed
Metropolitan of Thessalonica. He tended his flock in an apostolic manner for
some twelve years, and wrote many books and treatises on the most
exalted doctrines of our Faith; and having lived for a total of
sixty-three years, he reposed in the Lord in 1359.
