In the Acts of St. Balsamus, who died AD 331, there is an early example of the connection between baptism and the giving of a name. "By my paternal name", this martyr is said to have declared, "I am called Balsamus, but by the spiritual name which I received in baptism, I am known as Peter." The assumption of a new name was fairly common amongst Christians.
Eusebius the historian took the name Pamphili from
Pamphilus, the martyr whom he especially venerated. Earlier still
St. Cyprian chose to be called Cyprianus Caecilius out of gratitude to the Caecilius to whom he owed his conversion.
St. Dionysius of Alexandria (c. 260) declared, "I am of opinion that there were many of the same name as the
Apostle John, who on account of their love for him, and because they admired and emulated him, and desired to be loved by the Lord as he was, took to themselves the same name, just as many of the children of the faithful are called Paul or Peter." The assumption of any such new name would take place formally at baptism, in which the
catechumen, then probably as now, had to be addressed by some distinctive appellation, and the imposition of a new name at baptism had become general. Every child had necessarily to receive some name or other, and when baptism followed soon after birth this allowed public recognition of the choice made. In the thirtieth of the supposed
Arabian Canons of Nicaea: "Of giving only names of Christians in baptism"; but the sermons of
St. John Chrysostom assume in many different places that the conferring of a name, presumably at baptism, ought to be regulated by some idea of Christian edification, and he implies that such had been the practice of earlier generations. For example, he says: "When it comes to giving the infant a name, caring not to call it after the saints, as the ancients at first did, people light lamps and give them names and so name the child after the one which continues burning the longest, from thence conjecturing that he will live a long time" (Hom. in Cor., xii, 13). Similarly he commends the practice of the parents of
Antioch in calling their children after the martyr Meletius (
P.G. 50, 515) and urges his hearers not to give their children the first name that occurs, nor to seek to gratify fathers or grandfathers or other family connections by giving their names, but rather to choose the names of holy men conspicuous for virtue and for their courage before God (P.G. 53, 179). There are other historic examples of such a change of name in adult converts. Socrates (Hist. Eccl., VII, xxi) wrote of Athenais who married the Emperor
Theodosius the Younger, and who previously to marriage was baptized (AD 421) receiving the name Eudoxia.
Bede wrote that King
Caedwalla went to Rome and was baptized by the
Pope Sergius who gave him the name of Peter. Dying soon afterwards he was buried in Rome and his epitaph beginning
Hic depositus est Caedwalla qui est Petrus was pointed out (Bede, "Hist. Eccl.", V, vii). Later
Guthrum the Danish leader in England after his long contest with
King Alfred was eventually defeated, and consenting to accept Christianity was baptized in 878, taking the name Æthelstan. ==Practice regarding names==
