Matthew 14:26

"When the disciples," it is said, "saw Him walking on the sea, they were troubled, saying, It is a spirit: and they cried out for fear." Yea, and He constantly doth so; when He is on the point of removing our terrors, He brings upon us other worse things, and more alarming: which we see took place then also. For together with the storm, the sight too troubled them, no less than the storm. Therefore neither did He remove the darkness, nor straightway make Himself manifest, training them, as I said, by the continuance of these fears, and instructing them to be ready to endure. This He did in the case of Job also; for when He was on the point of removing the terror and the temptation, then He suffered the end to grow more grievous; I mean not for his children's death, or the words of his wife, but because of the reproaches, both of his servants and of his friends. And when He was about to rescue Jacob from his affliction in the strange land, He allowed his trouble to be awakened and aggravated: in that his father-in-law first overtook him and threatened death, and then his brother coming immediately after, suspended over him the extremest danger. For since one cannot be tempted both for a long time and severely; when the righteous are on the point of coming to an end of their conflicts, He, willing them to gain the more, enhances their struggles. Which He did in the case of Abraham too, appointing for his last conflict that about his child. For thus even things intolerable will be tolerable, when they are so brought upon us, as to have their removal near, at the very doors.

A confused noise and uncertain sound is the mark of great fear. But if, according to Marcion and Manichæus, our Lord was not born of a virgin, but was seen in a phantasm, how is it that the Apostles now fear that they have seen a phantasm (or vision)?

(Quæst. Ev. i. 15.) Or; That the disciples here say, It is a phantasm, figures those who yielding to the Devil shall doubt of the coming of Christ.

But Christ coming in the end shall find His Church wearied, and tossed by the spirit of Anti-Christ, and by the troubles of the world. And because by their long experience of Anti-Christ they will be troubled at every novelty of trial, they shall have fear even at the approach of the Lord, suspecting deceitful appearances. But the good Lord banishes their fear, saying, It is I; and by proof of His presence takes away their dread of impending shipwreck.
