Thebutes, or Thebuthis
All that is known of this person is the statement that Eusebius (Hist. Eccles
. 4:22) quotes from Hegesippus to the effect that Thebutes made a beginning secretly to corrupt the Church of Jerusalem, because Simon the son of Cleophas was appointed to be bishop of the Christians of that city instead of himself.
4. The same author also describes the beginnings of the heresies which arose in his time, in the following words: And after James the Just had suffered martyrdom, as the Lord had also on the same account, Symeon, the son of the Lord's uncle, Clopas, was appointed the next bishop. All proposed him as second bishop because he was a cousin of the Lord.
Therefore, they called the Church a virgin, for it was not yet corrupted by vain discourses.
5. But Thebuthis, because he was not made bishop, began to corrupt it. He also was sprung from the seven sects among the people, like Simon, from whom came the Simonians, and Cleobius, from whom came the Cleobians, and Dositheus, from whom came the Dositheans, and Gorthæus, from whom came the Goratheni, and Masbotheus, from whom came the Masbothæans. From them sprang the Menandrianists, and Marcionists, and Carpocratians, and Valentinians, and Basilidians, and Saturnilians. Each introduced privately and separately his own peculiar opinion. From them came false Christs, false prophets, false apostles, who divided the unity of the Church by corrupt doctrines uttered against God and against his Christ.
"Tebuthi" is also the patronimic for Jesus, potentially identified with the same Jesus ben Sapphat
