This return Christ makes to the Apostle for the testimony which Peter had spoken concerning Him, “Thou art Christ, the Son of the living God.” The Lord said unto him, “Blessed art thou, Simon Bar-jonas?” Why? Because flesh and blood has not revealed this unto thee, but My Father. That which flesh and blood could not reveal, was revealed by the grace of the Holy Spirit. By his confession then he obtains a title, which should signify that he had received a revelation from the Holy Spirit, whose son he shall also be called; for Barjonas in our tongue signifies The son of a dove.
Others take it in the simple sense, that Peter is the son of John [ed. note: In John 21, the Vulgate has ‘Johannis,’ but in John 1, 43, ‘Jona.’], according to that question in another place, “Simon, son of John, lovest thou me?” [John 21:15] affirming that it is an error of the copyists in writing here Barjonas for Barjoannas, dropping one syllable. Now Joanna is interpreted ‘The grace of God.’ But either name has its mystical interpretation; the dove signifies the Holy Spirit; and the grace of God signifies the spiritual gift.
