Hilary of Poitiers

That He commands His disciples to enter the ship and to go across the sea, while He sends the multitudes away, and after that He goes up into the mountain to pray; He therein bids us to be within the Church, and to be in peril until such time as returning in His splendour He shall give salvation to all the people that shall be remaining of Israel, and shall for give their sins; and having dismissed them into His Father’s kingdom, returning thanks to His Father, He shall sit down in His glory and majesty. Meanwhile the disciples are tossed by the wind and the waves; struggling against all the storms of this world, raised by the opposition of the unclean spirit.
