"The relation of liturgy to the apostolic age is obvious. It has flowed through the centuries like a ceaseless stream. It had its first deep sources in the synagogue. It is not only that a few words have remained in continuous use since that time, such as Amen, Hallelujah, and Hosanna, but the whole structural form of our order of worship shows clearly its relation to that worship which Jesus Himself shared in the synagogue at Nazareth and in which, as a grown man, he officiated when He was invited to read and interpret the Scriptures. To the ancient worship of the synagogue the apostolic church added the Holy Communion, that new creation which she received from the Saviour Himself and which is the center of all liturgy. As it is celebrated still, with the traditional chants, the Preface and the Sanctus, it is essentially a contribution of the first century."
From Swedish Bishop Bo Giertz's Pastoral Letter to the Diocese of Gothburg in 1949 (Herdabrev), published in English as 'Liturgy and Spiritual Awakening' (trans. C.A. Nelson).
The origins of the traditional Western liturgy in the ancient synagogue and the Apostolic age may be well-known to scholars and pastors, but how many of our lay people are aware of it? It is Giertz's purpose here in this Herdabrev to educate the laity of his diocese, after all. Having acknowledged the legitimacy of the lay concern for spiritual awakening and its apostolic origins (so often opposed in his day and ours to the so-called 'dead formalism' of liturgy), he then also points out that the liturgy is also the work of the same Spirit who inspires all genuine awakenings, and thus ought to be reverenced as the Spirit's gift to the church just as much as are 'revivals' of faith and piety.
Needless to say, there is much of relevance here to our contemporary 'worship wars' and the relation of charismatic and revival movements to the life of the church in our day. Would that the bishops and church presidents of today might take up, like Bishop Giertz, the mantle of authoritative teaching that is so sorely needed in this confused time.
