Then they willingly received him into the ship: and immediately the ship was at the land to which they went.
All Commentaries on John 6:21 Go To John 6
Cyril of Alexandria
AD 444
The Lord not only releases the voyagers from dangers, wondrously shining on them, but also frees them both from toil and sweat, by His God-befitting Power thrusting forward the ship on to the opposite shore. For they were expecting that by rowing on still, they should with difficulty be able to reach the end, but He releases them from these their toils, revealing Himself to them in a very little time the Worker of many miracles to their full assurance. When then Christ appears and beams upon us, we shall without any labour succeed even against our hope, and we who are in danger through not having Him, shall have no more need of toil to be able to accomplish what is profitable for us, when He is present. Christ then is our deliverance from all danger, and the accomplishment of achievements beyond hope to them that receive Him.
But since we have discoursed on every portion of the subject singly, come and let us, joining the meaning hereof with the connexion of the preceding portions, work out the spiritual interpretation. We said then that Jesus ascended into Heaven as into a mountain, that is to say, being received up, after His resurrection from the dead. But when this has taken place, then His disciples alone and by themselves, a type of Ecclesiastical teachers in succession throughout all time, swim through the billows of this present life as a kind of sea, meeting with varied and great temptations, and enduring no contemptible dangers of teaching at the hands of those who oppose the faith and war against the Gospel preaching: but they shall be freed both from their fear and every danger, and shall rest from their toils and misery, when Christ shall appear to them hereafter too in God-befitting Power, and having the whole world under His Feet. For this I deem His walking on the sea signifies, since the sea is often taken as a type of the world by Divine Scripture, as it is said in the Psalms, This great and wide sea, there are things creeping innumerable, both small and great beasts. When Christ then cometh in the glory of His Father, as it is written, then shall the ship of the holy Apostles, that is, the Church, and they that sail therein, i. e., they who through faith and love toward God are above the things of the world, without delay and without all toil, gain the land, whither they were going. For it was their aim to attain unto the Kingdom of Heaven, as to a fair haven. And the Saviour confirms this understanding of all that has been said, in that he says to His Disciples at one time, A little while and ye shall no more see Me, and again a little while and ye shall see Me, at another again, Tribulation shall ye have in the world, but be of good cheer, I have overcome the world. But in the night the Lord cometh down from the mountain and visiteth His disciples who are watching, and they look on Him coming, not without fear (for they tremble) that something needful for our understanding may in this too be made known unto us. For He shall descend from Heaven, as in the night, the world yet sleeping and slumbering in much sin. Therefore to us too doth He say, Watch therefore, for ye know not what hour your Lord doth come. The parable too of the Virgins will no less teach us this. For He says that five were wise, five foolish: but while the Bridegroom tarried, they all slumbered and slept: and at midnight there was a cry made, Behold, the Bridegroom cometh, go ye out to meet Him. Seest thou how at midnight the Bridegroom is announced to us? And what the cry is, and the mode of the meeting, the Divine Paul will make known, saying at one time, For the Lord Himself shall descend from heaven with a summons, with voice of archangel, with the trump of God, at another of the saints who are raised up, WE which are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air, and so shall we ever be with the Lord. But the disciples being smitten with fear, albeit they saw Him coming, and were found in toil and watching, signifies that the Judge will come terrible to all, and that the righteous man will surely quake within himself, proven as by fire, albeit ever foreseeing Him Who was to come, and not shrinking from toils in virtue, nourished in vigilance alike and good watching. But the Lord doth not enter into the ship with His disciples, as though He were going to sail with them, but rather moveth the ship on to the land. For Christ will not appear co-working any more with those who honour Him, unto their achievement of virtue, but to give to them that have already achieved their looked-for end.
