“Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected, the same is become the head of the corner: this is the Lord’s doing, and it is marvellous in our eyes?”
Matthew 21:42 — Greek Interlinear
Church Fathers on Matthew 21:42
The design of this further parable is to shew that their guilt was heinous, and unworthy to be forgiven.
The householder is God, who in some parables is represented as a man. As it were a father condescending to the infant lisp of his little child, in order to instruct him.
He is called man, by title, not by nature; in a kind of likeness, not in verity. For the Son knowing that by occasion of His human name He himself should be blasphemed as though he were mere man, spoke therefore of the Invisible God the Father as man; He who by nature is Lord of Angels and men, but by goodness their Father.
