These are spots: see 2 Peter 2:13. In your feasts of charity; feasts used among the primitive Christians, to show their unity among themselves, and promote and maintain mutual charity, and for relief of the poor among them. Feeding themselves without fear; unreasonably cramming themselves, without respect to God or the church. Clouds they are without water, carried about of winds; empty, making a show of what they have not, Proverbs 25:14; and inconstant: see 2 Peter 2:17. Trees whose fruit withereth; he compares them to trees, which having leaves and blossoms, make a show of fruit, but cast it, or never bring it to maturity, or it rots instead of ripening; so these here make a show of truth and holiness, but all comes to nothing. Without fruit; without any good fruit, (which only deserves to be called fruit), brought forth by them, either in themselves or followers, who never get any real benefit by them. Twice dead; wholly dead; dead over and over; dead by nature, and dead by that hardness of heart they have contracted, or that reprobate sense to which God hath given them up. Plucked up by the roots; and so never like to bear fruit, and fit only for the fire; it notes the incurableness of their apostacy, and their nearness to destruction.
