Joh 15, Verses 1–3English original
I am the true vine, and my Father is the husbandman. Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit. Now ye are clean through the word which I have spoken unto you.
(ix. de Trin) But He wholly separates this humiliation in the flesh from the form of the Paternal Majesty, by setting forth the Father as the diligent Husbandman of this vine: And My Father is the Husbandman.
