The zeal of some Christians, which was not according to knowledge, did not prevent the Church from making that progress which God destined from the beginning. The Christians, at first, celebrated their mysteries in sequestered houses, and in caves, and during the night. Hence, according to Minucius Felix, the title given them of _lucifugaces._ Philo calls them Gesséens. The names most frequently applied to them by the heathens, during the first four centuries, were "Galileans" and "Nazarenes"; but that of "Christians" has prevailed above all others. Neither the hierarchy, nor the services of the church, were established all at once; the apostolic times were different from those which followed. The mass now celebrated at matins was the supper performed in the evening; these usages changed in proportion as the church strengthened. A more numerous society required more regulations, and the prudence of the pastors accommodated itself to times and places. St. Jerome and Eusebius relate that when the churches received a regular form, five different orders might be soon perceived to exist in them--superintendents, _episcopoi_, whence originate the bishops; elders of the society, _presbyteroi_, priests, _diaconoi_, servants or deacons; _pistoi_, believers, the initiated--that is, the baptized, who participated in the suppers of the agape, or love-feasts; the _catechumens_, who were awaiting baptism; and the _energumens_, who awaited their being exorcised of demons. In these five orders, no one had garments different from the others, no one was bound to celibacy; witness Tertullian's book, dedicated to his wife; and witness also the example of the apostles. No paintings or sculptures were to be found in their assemblies during the first two centuries; no altars; and, most certainly, no tapers, incense, and lustral water. The Christians carefully concealed their books from the Gentiles; they intrusted them only to the initiated. Even the catechumens were not permitted to recite the Lord's prayer. _Of the Power of Expelling Devils, Given to the Church._ That which most distinguished the Christians, and which has continued nearly to our own times, was the power of expelling devils with the sign of the cross. Origen, in his treaties against Celsus, declares--at No. 133--that Antinous, who had been defied by the emperor Adrian, performed miracles in Egypt by the power of charms and magic; but he says that the devils came out of the bodies of the possessed on the mere utterance of the name of Jesus. Tertullian goes farther; and from the recesses of Africa, where he resided, he says, in his "Apology"--chap. xxiii.--"If your gods do not confess themselves to be devils in the presence of a true Christian, we give you full liberty to shed that Christian's blood." Can any demonstration be possibly clearer?
