simply because they failed to do justice to the gospel as disclosed in the New Testament.
There are a couple of problems with McGrath's account of the Reformed Churches' response to Arminianism. First, while the teaching of Arminius and the Remonstrants who followed in his wake threw up some new challenges, it was in some ways an old error. In effect Arminianism was Semi-Pelagianism in 17th century clothing. Second, in their Canons, the Synod of Dort produced a well thought-out biblical and theological rebuttal of Arminian error (the so-called Five Points of Calvinism). The Synod appealed to Scripture rather than attempting to resolve the controversy simply by counting heads.
