It may be asked, why after His resurrection He stood on the shore to receive the disciples, whereas before He walked on the sea? The sea signifies the world, which is tossed about with various causes of tumults, and the waves of this corruptible life; the shore by its solidity figures the rest eternal. The disciples then, inasmuch as they were still upon the waves of this mortal life, were labouring on the sea; but the Redeemer having by His resurrection thrown off the corruption of the flesh, stood upon the shore.
