 The formulation of the Five Points of Calvinism in the "Canons of Dort" has been attributed to Walaeus, Godefridus Udemans, and Jacobus Triglandius.In the aftermath of the Synod, Walaeus ministered to Johan van Oldenbarneveldt before his execution.Oldenbarneveldt, Grotius, and other leaders of the Remonstrants were sentenced to death; Walaeus was asked to communicate the sentence to Oldenbarneveldt, Grotius, and Rombout Hogerbeets.
