Jude 1:19

19.These be they who separate themselves. Some Greek copies have the participle by itself, other copies add ἑαυτοὺς, “themselves;” but the meaning is nearly the same. He means that they separated from the Church, because they would not bear the yoke of discipline, as they who indulge the flesh dislike spiritual life. (201) The word sensual, or animal, stands opposed to spiritual, or to the renovation of grace; and hence it means the vicious or corrupt, such as men are when not regenerated. For in that degenerated nature which we derive from Adam, there is nothing but what is gross and earthly; so that no part of us aspires to God, until we are renewed by his Spirit.
