John 19:1
1So Pilate then took Jesus and flogged him.
The flogging is not a last-ditch kindness that works. Pilate still hopes a beaten Jesus will satisfy the crowd without a cross. Classical Arminians read a political choice: a magistrate using lesser violence to dodge a greater injustice, and failing.
The innocent is already paying. Nothing in the scene says this suffering is a show. The world is watching a judge who knows better and still lays the lash on a man he will soon call guiltless.
Pilate adheres to his original intention, Calvin notes, adding a second ignominy in hope the Jews will be satisfied with a light chastisement. Heaven's decree, not Pilate's tactic, is carrying Christ toward death.
The judge's mouth will keep attesting innocence while his hand inflicts punishment. The substitution has begun in public: a sinless man is already treated as if he were the guilty party.
