Wise words from Bishop Bo Giertz:
It is important for us that both awakening and liturgy be given their proper and pristine Christian place in the life of the congregation. Awakening is always needed, not only because the church must always be a missionary church and reach out after those that are on the outside, but also because there is always the need for awakening even among the most faithful members of the church. The church has exactly as many sinners as she has members. The old Adam in each one of us is prone to fall asleep, to make the Christian life a dead routine, to use liturgical form to cloak his self-complacency and impenitence. It is not difficult to fashion a form of religion that suits the ego and allows the old Adam within to become sovereign again. One may go regularly to church and Holy Communion. One may cherish beautiful church music and lovely sanctuaries. One may be honestly convinced that one possesses the correct doctrine and loves the pure preaching of the Word. And at the same time one may be thoroughly obsessed by self-love, complacent with one's self, satisfied with one's own pious accomplishments and totally indifferent to the troubles and burdens of one's fellow men, which are so apparent before one's very eyes. The Holy Spirit always needs to awaken slumbering souls, stir up the dust, push the old Adam against the wall, and blow a new breath of life into the dead bones. Awakening is never superfluous, as long as we are in the flesh.
Liturgy is just as needful. There can be no normal church life without liturgy. Sacraments need form, the order of worship must have some definite pattern. It is possible to live for a short time on improvisations and on forms that are constantly changing and being made over. One may use only free prayers and yet create a new ritual for every worship situation. But the possibilities are soon exhausted. One will have to repeat, and with that the making of rituals is in full swing. In circles where people seek to live without any forms, new forms are nevertheless constantly taking shape. Favorite songs are used again and again with monotonous regularity, certain prayer expressions are constantly repeated, traditions take form and traditional yearly ceremonies are observed. But it would not be wrong to say that the new forms that grow up in this way are usually less attractive and more profane than the ancient liturgy. They contain less of God's Word, they pray and speak without Scriptural direction, they are not so much concerned about expressing the whole content of Scripture, but are satisfied with one thing or another that seems to be especially attractive or popular. The new liturgy that grows in this manner is poorer, less Biblical, and less nourishing to the soul than the discarded ancient order.
Revival and liturgy, therefore, have each their given place in the church. They must go hand in hand. This does not prevent liturgy from sometimes becoming an enemy of awakening, just as awakening can be a foe of liturgy.
