The expression “earthly things,” some say is here used of the wind; that is, “If I have given you an example from earthly things, and ye did not even so believe, how shall ye be able to learn sublimer things?” And wonder not if He here call Baptism an “earthly” thing, for He calls it so, either from its being performed on earth, or so naming it in comparison with that His own most awful Generation. For though this Generation of ours is heavenly, yet compared with that true Generation which is from the Substance of the Father, it is earthly.
