Peter Martyr Vermigli was an Italian-born Reformed theologian. His early work as a reformer in Catholic Italy and his decision to flee for Protestant northern Europe influenced many other Italians to convert and flee as well. In England, he influenced the Edwardian Reformation, including the Eucharistic service of the 1552 Book of Common Prayer. He was considered an authority on the Eucharist among the Reformed churches, and engaged in controversies on the subject by writing treatises. Vermigli's Loci Communes, a compilation of excerpts from his biblical commentaries organised by the topics of systematic theology, became a standard Reformed theological textbook.
Predestination is a doctrine in Calvinism dealing with the question of the control that God exercises over the world. In the words of the Westminster Confession of Faith, God "freely and unchangeably ordained whatsoever comes to pass." The second use of the word "predestination" applies this to salvation, and refers to the belief that God appointed the eternal destiny of some to salvation by grace, while leaving the remainder to receive eternal damnation for all their sins, even their original sin. The former is called "unconditional election", and the latter "reprobation". In Calvinism, some people are predestined and effectually called in due time to faith by God, all others are reprobated.

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.
