 In 1615 Walaeus published "Het Ampt der Kerckendienaren", against the leading Remonstrant and ally of Grotius, Johannes Wtenbogaert, taking up the relationship of church and state.It replied to the "Ampt ende Authoriteyt" of Wtenbogaert, but also implicitly took aim at the "Pietas Ordinum" of Grotius.Its tone was quite peaceable and open to compromise; the work put Walaeus at the centre of the theological debate, but Wtenbogaert decided on a polemical reply.
