However, Dan states:
TF notes well the WCF is open to supra, but WCF is also open to unlimited atonement. It was written such that both 5 point Calvinists and 4 pointers would be satisfied. TF himself has noted Arminius' influence on Amyraldianism. So that's another way in which Arminius impacted Calvinism.No, the WCF is not open to unlimited atonement. The WCF states:
To all those for whom Christ hath purchased redemption, he doth certainly and effectually apply and communicate the same; making intercession for them, and revealing unto them, in and by the Word, the mysteries of salvation; effectually persuading them by his Spirit to believe and obey; and governing their hearts by his Word and Spirit; overcoming all their enemies by his almighty power and wisdom, in such manner and ways as are most consonant to his wonderful and unsearchable dispensation.- Westminster Confession of Faith, Chapter 8, Paragraph 8
Similarly, the Westminster Larger Catechism explains:
Q. 59. Who are made partakers of redemption through Christ?- Westminster Larger Catechism, Question/Answer 59
A. Redemption is certainly applied, and effectually communicated, to all those for whom Christ hath purchased it; who are in time by the Holy Ghost enabled to believe in Christ according to the gospel.
So, no. While Arminius may have been an influence on Amyraut and the school of Saumur, the Amyraldian position is excluded by the Westminster Confession of Faith.
