“Hence, also, in the number of the large fishes which our Lord, after His resurrection, showing this new life, commanded to be taken on the right side of the ship, there is found the number fifty, three times multiplied with the addition of three more [the symbol of the Trinity] to make the holy mystery more apparent; and the disciples’ nets were not broken, because in that new life there shall be no schism, caused by the disquiet of heretics. Then [in this new life] man, made perfect and at rest, purified in body and in soul, by the pure words of God which are like silver purged from its dross, seven times refined, shall receive his reward, the denarius. So that with that reward the numbers ten and seven meet in Him. For in this number seventeen [there is found] as in other numbers representing a combination of symbols, a wonderful mystery. Nor is it without good reason that the seventeenth Psalm is the only one which is given complete in the Book of Kings, because it signifies that kingdom in which we shall have no enemy. For its title is, ‘A Psalm of David in the day that the Lord delivered him from the hand of all his enemies and from the hand of Saul.’ For of whom is David the type, but of Him who, according to the flesh, was born of the seed of David? He, in His church, that is, in His body, still endures the malice of enemies. Therefore the words which from heaven fell upon the ear of that persecutor whom Jesus slew by His voice, and whom He transformed into a part of His body (as the food which we use becomes a part of ourselves), were these: ‘Saul, Saul, why persecutest thou me?’ And when shall this His body be finally delivered from enemies? Is it not when the last enemy, death, shall be destroyed? It is to that time that the number of the one hundred and fifty-three fishes pertains. For if the number seventeen itself be the side of an arithmetical triangle, formed by placing above each other rows of units, increasing in number from one to seventeen, the whole sum of these units is one hundred and fifty-three: since one and two make three; three and three, six; six and four, ten; ten and five, fifteen; fifteen and six, twenty-one; and so on: continue this up to seventeen, the total one hundred and fifty-three.”[59]
