Life and Career
Cabasilas belonged to the cultivated lay society of late Byzantine Thessalonica and Constantinople. He was the kinsman—described as the nephew—of Neilos Cabasilas, himself a theologian and clergyman, and the family was firmly opposed to union between the Greek and Latin churches.
In his earlier years he engaged in the public and political life of the empire and stood on intimate terms with the emperor John VI Kantakouzenos, accompanying him when the emperor laid down his throne and retired to a monastery. The precise nature of his own ecclesiastical standing remains uncertain in the sources: he was once thought to have succeeded his uncle as archbishop of Thessalonica around 1355, but it is now considered more likely that he served rather as a priest at the Mangana Monastery in Constantinople and remained, in the main, a layman. He is commemorated in the Church under the rank of the Righteous.
