Therefore that disciple whom Jesus loved said unto Peter, It is the Lord. Now when Simon Peter heard that it was the Lord, he girded his fisher's coat unto him, (for he was naked,) and did cast himself into the sea.

AD 444
Again, in this passage, the writer of this book calls himself the beloved disciple----and he would seem to have been thus well beloved on account of his great discernment and purity of mind, and the keenness of his mental vision, and a disposition which enabled him readily to grasp the truth. And, in fact, he seized the meaning of the sign before the rest, and perceived Christ's Presence, and told the rest, entertaining not a shadow of doubt, but crying out to them with a very confident voice, It is the Lord. The inspired Peter leapt into the sea, thinking that to go by the ship would cause delay, for he was always fervent in zeal, and easily stirred up to confidence and love of Christ. The rest followed his lead, with the ship, dragging the net. Then they see a fire of coals, for the Saviour had kindled a fire miraculously, and put a fish upon it that He had caught by His ineffable power; and this too He had done of design. For it was not the hand of the holy Apostles, or the preaching of these spiritual fishermen among men, but the power of the Saviour that started the work. For He first caught one as the firstfruits of those who were to come (not that we mean one precisely, for by one is signified a small number), then afterwards the disciples caught the multitude in their nets, being enabled by His Divine bidding to take something of what they sought. Peter then hauls up the net; by which it was to be understood, that the labour of the holy Apostles would not be without its effect. For they put the mass of captured fish before Him Who had commanded them to be caught; and the quantity of the fish is indicated by the number 153. The number 100, to the best of my judgment, signifies the complement of the nations, for the number 100 is a very perfect number, being compounded of 10 times 10; and for this reason our Lord Jesus Christ Himself, in one place, speaks in the parable of having 100 sheep belonging to Him, signifying the complete sum of rational creatures, and in another place declares that the best ground will bring forth a hundredfold, meaning thereby the perfect fertility of the righteous soul. The number 50, on the other hand, betokens the elect remnant of the Israelites, saved by grace; for 50 is half 100, and falls short of the perfect number in amount. And by the three, reference is made to the Holy and Consubstantial Trinity, the number alone showing this; for to the glory and ceaseless praise of the Trinity the life of those who have been taken captive through faith is consecrated, and implies connexion with the Godhead. For God is in all those who believe in Him, and keeps nigh unto Him, by means of sanctification, those who have been won over by the teaching of the Gospel. And when the net had been drawn up, our Lord said again to the holy disciples: Come and break your fast; thereby teaching them, that after their pain and tribulation in gathering in those who were called and saved, they should sit down with Him, as the Saviour Himself said, and their table would be spread with food such as no tongue can name, the spiritual, that is, and Divine, and that passeth man's understanding. Christ also wishes to imply that which is said by the Psalmist: Thou shalt eat the fruit of the labours of thy hands. They did not take food for themselves, and eat thereof, but Christ gave to them of it; that we might learn, as in a type, that on that day Christ will Himself provide us with Divine blessings, and apportion unto us those things which may be profitable unto us as our Lord.
