In theory, style, usage, and probably to some extent in actual melodies also, the music of the primitive Church forms an unbroken line with the music of pre-Christian antiquity. The relative proportion contributed by Jewish and Greek musical practice cannot be known. There was at the beginning no formal break with the ancient Jewish Church; the disciples assembled regularly in the temple for devotional exercises; worship in their private gatherings was modelled upon that of the synagogue which Christ himself had implicitly sanctioned. The synagogical code was modified by the Christians by the introduction of the eucharistic service, the Lord’s Prayer, the baptismal formula, and other institutions occasioned by the new doctrines and the “spiritual gifts.” At Christ’s last supper with his disciples, when the chief liturgical rite of the Church was instituted, the company sang a hymn which was unquestionably the “great Hallel” of the Jewish Passover celebration.[29] The Jewish Christians clung with an inherited reverence to the venerable forms of their fathers’ worship; they observed the Sabbath, the three daily hours of prayer, and much of the Mosaic ritual. In respect to musical usages, the most distinct intimation in early records of the continuation of ancient forms is found in the occasional reference to the habit of antiphonal or responsive chanting of the psalms. Fixed forms of prayer were also used in the apostolic Church, which were to a considerable extent modelled upon the psalms and the benedictions of the synagogue ritual. That the Hebrew melodies were borrowed at the same time cannot be demonstrated, but it may be assumed as a necessary inference. With the spread of the Gospel among the Gentiles, the increasing hostility between Christians and Jews, the dismemberment of the Jewish nationality, and the overthrow of Jewish institutions to which the Hebrew Christians had maintained a certain degree of attachment, dependence upon the Jewish ritual was loosened, and the worship of the Church came under the influence of Hellenic systems and traditions. Greek philosophy and Greek art, although both in decadence, were dominant in the intellectual life of the East, and it was impossible that the doctrine, worship, and government of the Church should not be gradually leavened by them. St. Paul wrote in the Greek language; the earliest liturgies are in Greek. The sentiment of prayer and praise was, of course, Hebraic; the psalms formed the basis of all lyric expression, and the hymns and liturgies were to a large extent colored by their phraseology and spirit. The shapeliness and flexibility of Greek art, the inward fervor of Hebrew aspiration, the love of ceremonial and symbolism, which was not confined to any single nation but was a universal characteristic of the time, all contributed to build up the composite and imposing structure of the later worship of the Eastern and Western churches.
