A side note here:
Doulos_tou_kuriou refers to the American/US Lutheran churches when talking about "the Lutheran church". The European Lutheran churches -- the Evangelical-Lutheran Churches of Denmark, Estonia, Finland, Iceland, Lithuania, Norway, and Sweden -- have never stopped believing in the Apostolic Succession, signified in the ordination/consecration of a bishop, and the episcope, as a visible sign expressing and serving the Church's unity and continuity as the One, Holy, Catholic and Apostolic Church.
In the Lutheran diversity in worship, my Evangelical Lutheran Church of Finland is squarely in the traditional/"high church" end of the spectrum. Our liturgy follows the 16th century Mass, no improvisations -- not even for the Metal Mass.
