Desposyni is built on despotēs, the master of a house. The desposyni are the ones who belong to the Master: the blood family of Yeshua, His mother, His brothers Ya'akov and Yosef and Shimon and Yehudah, and their descendants. The Gospels name the household plainly (Mark 6:3). Acts places the family in the upper room from the beginning (Acts 1:14), Sha'ul (Paul) mentions the brothers traveling with wives as a known class of workers (1 Corinthians 9:5), and calls Ya'akov the brother of the Lord to date his own visit (Galatians 1:19).

The title itself is preserved by Julius Africanus, writing in the early third century, who reports that the surviving kin still carried the name in his own day and kept their Davidic genealogy from memory. Notice what kind of name it is. It designates a household, not an office. It could not be conferred, inherited by vote, or reassigned by a council, which is precisely why the later church, busy building offices, let the desposyni fade from its story. They are the standing reminder that the movement began as a family holding something in trust, and that belonging to the Master was always a matter of custody rather than rank.
