[cappie]

c.107-117 St. Ignatius of Antioch, apostolic Father and bishop. He was a disciple of St. John, along with St. Polycarp. Theodoret, the Church historian says he was consecrated bishop by St. Peter, who was at first bishop of Antioch before going to Rome. Ignatius was martyred in Rome under Emperor Trajan's rule. It was during the journey to Rome that he wrote his famous letters that contain invaluble information about the early Church. He was the first to use the term "Catholic" to describe the Church.

[b]Ignatius of Antioch:[/b]
"Let no one do anything of concern to the Church without the bishop. Let that be considered a valid Eucharist which is celebrated by the bishop or by one whom he ordains [i.e., a presbyter]. Wherever the bishop appears, let the people be there; just as wherever Jesus Christ is, there is the Catholic Church" ([i]Letter to the Smyrneans[/i] 8:2 [A.D. 110]).
