Is the Liturgy Really "Adiaphora"?

Pastor Randy Asburry, on his blog RAsburry's Res, has a short, insightful post on the liturgy titled "Is the Liturgy Really 'Adiaphora'?" I hope you'll check it out. Here's a couple of quotes:

But if we Lutherans take the Augsburg Confession at all seriously, we may want to repent of our mistaken notion of liturgy as "adiaphora" modernly interpreted. No, God has not dictated a specific form of liturgy, but He has indeed seen fit for 20 centuries to have His Church hand down liturgical forms that faithfully confess Jesus Christ and His eternal love of saving sinners by forgiving them and restoring them to life with Himself.

So, the point of the liturgy is not "liturgy for the sake of the liturgy." Rather, the point of the liturgy is faithfully to confess the mighty deeds of our Lord's salvation and to keep us centered in them. And for this reason, observing the Church's historic liturgy (as opposed to the forms of American evangelicalism/Pentecostalism) is a fundamental matter of our Lutheran confession of the faith and quite essential to the Christian faith and life, even to the mission of the Church.
