English: The current debate on a reformed liturgy is driven by opposition. On the one hand,
some protagonists for renewal embrace anything new that works, while on the other
hand traditionalists reject attempts to renew the liturgy, arguing that such efforts go
against the reformed liturgy. The question, however, is raised: “What is a reformed
liturgy?” The article endeavours to indicate principles for renewal, based on reformed
theology and not on the reformed tradition.
