Pilate knew he was innocent. Pilate's wife knew he was innocent, which is why she had a nightmare. The people all knew he was innocent, which was why they delivered him to Pilate: they were envious. When the false witnesses came forth, and he made no defense, Pilate was amazed. Everybody knew he was innocent.
His blood be on us and on our children.
That's what the guilty mob cried, and, ironically, that is what has happened, but not in the way they meant it.
His blood covers us and our children, his innocent, holy blood: it covers our guilt and the guilt of our children.
We go free, because he was condemned. We gain life, because he died. We are aquitted, because he was innocent.
And his resurrection on the third day, besides bringing Life to life and bringing Immortality to light; besides bringing joy to the sorrowing, does another important thing: it verifies his innocence: even the Father knew it.
And therefore the Father knows also that we go free, gain life, and are acquitted.
He was innocent, and by the inestimable gift of His sacrifice, we reap the rewards of his innocence. This is the Gospel.
