A contemporary understanding of what it means to be Lutheran in terms of the liturgy, then, assiduously arms the freedom that is ours under the gospel on the one hand. On the other, Lutheran liturgical understanding regards highly the liturgical heritage of catholic Christianity, in its freedom adapting it as necessary to the changing exigencies of history and culture, but treasuring and conserving it with all deliberateness for its time proven utility and for the continuity it visibly proclaims with the Church catholic of ages past. To borrow a phrase from Charles Porterfield Krauth, the continuity of the Lutheran liturgy is one of the most visible aspects of the grace given the “conservative reformation.” (From the WELS website)
