In the Roman Canon, after Simon and Jude, we find five Popes listed. The first of these are Linus Cletus.
St. Linus, the first successor of St. Peter in the See of Rome and, therefore, the second Pope, is assuredly the same from whom St. Paul sends a salutation to Timothy. He was converted to Christianity by St. Peter, and, as a distinguished assistant of the Prince of the Apostles, he may indeed frequently have taken his place, when the latter was obliged to leave Rome for a time, in order to preach the Gospel elsewhere. St. Linus led the Church from 67 to about 76. He was decapitated and buried in the Vatican by the side of St. Peter. Under Pope Urban VIII, a tomb was discovered there, bearing the simple inscription: “Linus.” His feast occurs on the twenty-third of September.
St. Cletus (76~91) succeeded St. Linus. The exact order of the early Popes is difficult to determine owing to the fact of persecution of the Church, including the burning of documents, and the use of slightly differing names between the Latin and Greek records. It is believed that he erected a tombstone to St. Peter, who had ordained him a Priest. His feast falls on the twenty-sixth of April.
St. Linus and St. Cletus, pray for us!
For the Greater Glory of God,
