Jude; called also Lebbaeus, and Thaddaeus, Mat_10:3.
The servant of Jesus Christ; not only in the general notion, as a believer, but in a more special, as an apostle. Priests and prophets in the Old Testament are peculiarly called God's servants, Psa_134:1-3Amo_3:7; and so are ministers in the New, 2Ti_2:24.
And brother of James; that James who was the son of Alphaeus, Mat_10:3. He mentions his brother to distinguish himself from Judas Iscariot; and his brother rather than his father, because James was most famous in the church, Act_15:1-41 Gal_2:91Co_9:5; as likewise to show his consent with his brother in his doctrine, and to make his Epistle the more acceptable.
To them that are sanctified by God the Father, viz. as the prime efficient cause of sanctification, which he works in believers by the Son, through the Spirit.
And preserved in Jesus Christ: their salvation, and perseverance, and deliverance from dangers, not being in their own power; he intimates, that Christ was appointed to be their King, and Head, and Keeper, the Author and Finisher of their faith, Heb_12:2, and furnished with power for their protection and security, and that by him they were kept unto the salvation purchased for them, viz. by his powerful operation and gracious influence maintaining their faith and union with himself.
And called, with an effectual calling, the beginning of their sanctification, before mentioned. The copulative, and, is not in the Greek; and the words may be read, sanctified by God the Father, preserved in Jesus Christ, as being called; and so called may be understood as going before the other two; and then the sense is, to the called, sanctified by God the Father, and preserved in Jesus Christ; or, to them who, being called, are sanctified, &c.
