What, then, is the specific essence, character, and form of Reformed liturgy? It is COVENANTAL. Rev. Van Dooren ends the introduction of this book with the following paragraph: We conclude with another quotation from C. Trimp, p. 12: Liturgical questions demanded the attention of the re-formed Churches even before Creeds and a Catechism. It was in her re-formed liturgy that the re-formed Churches presented themselves to the world, also the world of the false church.
