The Praise & Worship genre is surprisingly old.

Once upon a time, I stood at the altar in Trelleborg's church together with Axel Malmberg, who is now the vicar in Klippan, and he greeted the congregation with the ordinary liturgical salutation: “The Lord be with you.” It was a situation that I had often experienced before and never thought anything about, but this time the question came to me: “Shall I answer with the congregation? Shall I answer with the words ‘With you also the Lord ’, [trans. note: the traditional response in the salutation in Sweden is Med dig vare ock Herren] or am I one liturgical person with the other priest at the altar, so that instead I should receive with my brother in the office the congregation's response.”

These guys argue that there are apparently liturgical Lutherans who find their righteousness not in Christ, but rather in their own decision to use traditional, liturgical worship and hymnody.
