Jamieson, Fausset and Brown on 1 Timothy 3:6

6. not a novice--one just converted. This proves the Church of Ephesus was established now for some time. The absence of this rule in the Epistle to Titus, accords with the recent planting of the Church at Crete. Greek, "neophyte," literally, "a young plant"; luxuriantly verdant (Ro 6:5; 11:17; 1Co 3:6). The young convert has not yet been disciplined and matured by afflictions and temptations. Contrast Ac 21:16, "an old disciple."

lifted up with pride--Greek, literally, "wrapt in smoke," so that, inflated with self-conceit and exaggerated ideas of his own importance, he cannot see himself or others in the true light (1Ti 6:4; 2Ti 3:4).

condemnation of the devil--into the same condemnation as Satan fell into (1Ti 3:7; 2Ti 2:26). Pride was the cause of Satan's condemnation (Job 38:15; Is 14:12-15; Joh 12:31; 16:11; 2Pe 2:4; Jude 6). It cannot mean condemnation or accusation on the part of the devil. The devil may bring a reproach on men (1Ti 3:7), but he cannot bring them into condemnation, for he does not judge, but is judged [Bengel].
