The comparison, found in the Gospel of St. John, of the
Son to a Vine and the Father to a husbandman, must be understood with
reference to the Incarnation. To understand it with reference to
the Divine Generation is to doubly insult the Son, making Him inferior
to St. Paul, and bringing Him down to the level of the rest of mankind,
as well as in like manner the Father also, by making Him not merely to
be on one footing with the same Apostle, but even of no account at
all. The Son, indeed, in so far as being God, is also the
husbandman, and, as regards His Manhood, a grape-cluster. True
statement of the Father’s pre-eminence.
