And he arose—literally, he awoke ( διεγερθεὶς)—and rebuked the wind, and said unto the sea, Peace, be still ( σιώπα πεφίμωσο); literally, Be silent! be muzzled! The Greek perfect implies that before the word was uttered, the thing was done by the simple fiat of his will preceding the word.
The combined descriptions of the synoptists show that the storm was very violent, such as no human power could have composed or stilled. So that these words indicate the supreme authority of Christ as God, ruling the sea with his mighty power.
Thus Christ shows himself to be God. In like manner, Christ is able to overrule and control the persecutions of the Church and the temptations of the soul. St. Augustine says that "when we allow temptations to overcome us, Christ sleeps in us.
We forget Christ at such times. Let us, then, remember him. Let us awake him. He will speak. He will rebuke the tempest in the soul, and there will be a great calm." There was a great calm. For all creation perceives its Creator.
He never speaks in vain. It is observable that, as in his miracles of healing, the subjects of them usually passed at once to perfect soundness, so here, there was no gradual subsiding of the storm, as in the ordinary operations of nature, but almost before the word had escaped his lips there was a perfect calm.
