One clue - the CORE worm logos that I use.
From What Sasse Said
Confession & Liturgy
Confession and liturgy belong inseparably together if the church is to be healthy. Liturgy is prayed dogma; dogma is the doctrinal content of the liturgy. The placement of liturgy above dogma, for which one hears calls in the liturgical movements of all confessions with the well-known saying "lex orandi lex credendi"..., has been opposed in the Roman Church by the present Pope Pius XII] in his encyclical "Mediator Dei", in which he points out that one can also turn this saying around and that in all circumstances dogma should be the norm for the liturgy. If that is already known in Rome, how much more should it be known in the church that makes...the right understanding of the Gospel also the criterion for the liturgy.
