Jude 1:19

These be. Or, “these are.” The Greek is the same as in v. 16.

Separate themselves. Or, “make divisions,” that is, those who cause factions in the church in pursuit of their own ends. He who harbors ungodly ambitions has little scope for the fulfillment of his designs in a united church. Accordingly, he seeks opportunities to promote divisions among the members. True spiritual life goes out when factions come in (cf. 1 Cor. 1:10–13).

Sensual. Gr. psuchikoi (see on 1 Cor. 15:44; James 3:15). Psuchikoi stands in apposition with the expression “having not the Spirit,” that is, unspiritual persons.

The Spirit. Literally, “Spirit.” It is possible to interpret Jude’s words as “not having spiritual life,” in accord with the previous thought of the unspiritual nature of the false teachers. But the reference to the Holy Ghost in v. 20 makes it probable that Jude has the Holy Spirit in mind here also. It is certainly true that those who cause divisions in the church and are themselves unspiritual will not be possessed by the Holy Spirit.
