Again, the baptismal rite is a form of purification of world-wide prevalence, as has been already intimated. The washing of the new-born has been generally interpreted as a purgation of dangerous and evil influence among the lower as well as the higher races. An interesting form of such lustration is {157} recorded of the old Aztec home-life: the midwife washed the infant with the prayer, “May this water purify and whiten thy heart: may it wash away all that is evil.”[157.1] The adult, before initiation into any mystic society, usually needed elaborate purification; and this often took the form of baptism with water and occasionally with blood: and in certain of the Mediterranean religions the lustration was not merely regarded as a washing away of the old sin, but as a spiritual rebirth.[157.2] In the Isis rites the baptism with water was supposed to raise the mortal to the divinity: in the description of the baptismal purification of Setis I. the words occur: “I have purified thee with life and power, so as to make thee young, like thy father Ra.” And the gods themselves were believed to be reborn through the sprinkling of lustral water over their images.[157.3] We discover the same theories held by the {158} early Church concerning the Christian rite: the font washes away the taint of the flesh, while at the same time the divine potency of the water revivifies and recreates the catechumen, who dies to the old life and is born again; so that the font, which itself was exorcised and purified in the early period, was in some sense the womb of spiritual life, and the rite is both an exorcism and a communion. Very soon in the history of the Church it came to be regarded as of such serious and critical significance that the catechumen must prepare himself for it by prior purifications and exorcisms: such ceremonies as the breathing on his forehead by the priest, the sacramental partaking of the salt, the anointing with oil, together with the utterance of a prayer that “the enemy might be put to flight,” have an obvious cathartic significance.[158.1]
