The history of the Calvinist–Arminian debate begins in early 17th century in the Netherlands with a Christian theological dispute between the followers of John Calvin and Jacobus Arminius, and continues today among some Protestants, particularly evangelicals. The debate centers around soteriology, or the study of salvation, and includes disputes about total depravity, predestination, and atonement. While the debate was given its Calvinist–Arminian form in the 17th century, issues central to the debate have been discussed in Christianity in some form since Augustine of Hippo's disputes with the Pelagians in the 5th century.
