Catena Aurea · Johannesevangelium 1
He first findeth his own brother Simon, and saith unto him, We have found the Messias, which is, being interpreted, the Christ. And he brought him to Jesus. And when Jesus beheld him, he said, Thou art Simon the son of Jona: thou shalt be called Cephas, which is by interpretation, A stone.
Or perhaps He does not actually give him the name now, but only fixes beforehand what He afterwards gave him when He said, Thou art Peter, and upon this rock will I build My Church. And while about to change his name, Christ wishes to shew that even that which his parents had given him, was not without a meaning. For Simon signifies obedience, Joanna grace, Jona a dove: as if the meaning was; Thou art an obedient son of grace, or of the dove, i. e. the Holy Spirit; for thou hast received of the Holy Spirit the humility, to desire, at Andrew’s call, to see Me. The elder disdained not to follow the younger; for where there is meritorious faith, there is no order of seniority.
