of the Apostles. Paulus may be an intentional reference to St. Paul, and Johannes, Andreas, and Petrus with derivatives such as Petronia, Petrius, Petronilla, etc. may also refer to the Apostles. The name of Mary occurs occasionally in the catacomb inscriptions towards the end of the 4th century, for example, in the form LIVIA MARIA IN PACE, and there is a martyr Maria assigned to the date AD 256. Change of name at baptism 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
