Quadratus

Quadratus, known in Greek as Kodratos, was an early Christian teacher of the late first and early second centuries and, according to later ecclesiastical writers, bishop of Athens in the Roman province of Achaea. He belongs to the generation of the Apostolic Fathers, those figures who stood in living memory of the apostles. Eusebius of Caesarea, writing in the early fourth century, presents him as a disciple of the apostles and quotes from an apology Quadratus addressed to the emperor Hadrian. Jerome, in De viris illustribus, likewise names Quadratus as author of that apology and as bishop of Athens after Publius. Eastern hagiographical tradition further identifies him with one of the Seventy Apostles. Nothing reliable is known of his parentage, the place or date of his birth, or his education. Even the identification of the apologist with the Athenian bishop, though long customary in the churches, is not demonstrated by strictly contemporary documents.

The apology itself is lost except for a single fragment preserved by Eusebius in the fourth book of the Ecclesiastical History. In that fragment Quadratus argues that the works of the Saviour were genuine and not illusory, because those who had been healed and those who had been raised from the dead were seen not only at the moment of the miracle but remained alive for a considerable time, some even until Quadratus’s own day. The work is generally placed in the 120s, in connection with Hadrian’s presence in Athens or in the eastern provinces, when, Eusebius says, certain persons were troubling the Christians. Eusebius states that copies of the apology were still widely available in his time and that it displayed both intelligence and apostolic orthodoxy. Together with the nearly contemporary apology of Aristides, it stands at the head of the literary defense of Christianity before the Roman imperial authorities.

Whether Quadratus the apologist was the same man as Quadratus the bishop of Athens cannot be settled with certainty. Eusebius, in a different notice, records that after the martyrdom of Publius a Quadratus was appointed bishop of Athens and that by his zeal he gathered together the flock that had been scattered. Later writers fused the two notices into a single life. As bishop he would have shepherded a small urban community in a city still dominated by pagan philosophical schools and the imperial cult. No sermons, letters, or conciliar acts of his episcopate survive. The second-century church of Athens is otherwise poorly documented, which makes Quadratus one of the few named figures connecting that church to the apostolic age.

Later liturgical and martyrological texts, especially in the Greek East, add that Quadratus evangelized in Asia Minor, notably at Magnesia, and that he suffered martyrdom, sometimes described as death by stoning. These details do not appear in Eusebius or Jerome and must be treated as later tradition rather than as established fact. In the West the Roman Martyrology commemorates him on 26 May as a disciple of the apostles who, by his faith and labour, gathered the churches scattered under Hadrian and presented to the emperor a book in defense of the Christian religion. In the Eastern Orthodox Church he is honoured on 21 September as bishop of Athens and apostle of the Seventy, and again on 4 January with the rest of the Seventy. He was venerated as a saint from late antiquity; there was no medieval or modern process of beatification or canonization by a named pope.

Because so little of his writing remains, Quadratus’s historical importance lies chiefly in the fragment Eusebius saved and in his place at the beginning of Christian apology. The claim that some of those healed or raised by Jesus lived into the early second century has been cited by later theologians as a testimony to the public character of the Gospel miracles, though its value as independent historical evidence is limited by the loss of the full work and by the brevity of the quotation. Modern scholarship continues to debate the unity of the various men named Quadratus in early Christian literature—including a later martyr of Corinth commemorated on 10 March—and the exact circumstances in which the apology was delivered. What can be said with confidence is that a Christian named Quadratus, of apostolic connections and Athenian association, composed one of the earliest known defences of the faith before a Roman emperor, and that the churches of East and West have remembered him as a saint and bishop from a very early date.
