Protestant theological system and an approach to the Christian life named after John Calvin
The 5 Points of Calvinism, from Wikipedia:
- Total depravity: This doctrine, also called "total inability", asserts that as a consequence of the fall of man into sin, every person born into the world is enslaved to the service of sin. People are not by nature inclined to love God with their whole heart, mind, or strength, but rather all are inclined to serve their own interests over those of their neighbor and to reject the rule of God. Thus, all people by their own faculties are morally unable to choose to follow God and be saved because they are unwilling to do so out of the necessity of their own natures. (The term "total" in this context refers to sin affecting every part of a person, not that every person is as evil as possible.) This doctrine is borrowed from Augustine who was a member of a Manichaean sect in his youth.
- Unconditional election: This doctrine asserts that God has chosen from eternity those whom he will bring to himself not based on foreseen virtue, merit, or faith in those people; rather, it is unconditionally grounded in God's mercy alone. God has chosen from eternity to extend mercy to those He has chosen and to withhold mercy from those not chosen. Those chosen receive salvation through Christ alone. Those not chosen receive the just wrath that is warranted for their sins against God
- Limited atonement: Also called "particular redemption" or "definite atonement", this doctrine asserts that Jesus's substitutionary atonement was definite and certain in its design and accomplishment. This implies that only the sins of the elect were atoned for by Jesus's death. Calvinists do not believe, however, that the atonement is limited in its value or power, but rather that the atonement is limited in the sense that it is designed for some and not all. Hence, Calvinists hold that the atonement is sufficient for all and efficient for the elect. The doctrine is driven by the Calvinistic concept of the sovereignty of God in salvation and their understanding of the nature of the atonement.
- Irresistible grace: This doctrine, also called "efficacious grace", asserts that the saving grace of God is effectually applied to those whom he has determined to save (that is, the elect) and, in God's timing, overcomes their resistance to obeying the call of the gospel, bringing them to a saving faith. This means that when God sovereignly purposes to save someone, that individual certainly will be saved. The doctrine holds that every influence of God's Holy Spirit cannot be resisted, but that the Holy Spirit, "graciously causes the elect sinner to cooperate, to believe, to repent, to come freely and willingly to Christ."
- Perseverance of the saints: Perseverance (or preservation) of the saints (the word "saints" is used in the Biblical sense to refer to all who are set apart by God, and not in the technical sense of one who is exceptionally holy, canonized, or in heaven). The doctrine asserts that since God is sovereign and his will cannot be frustrated by humans or anything else, those whom God has called into communion with himself will continue in faith until the end. Those who apparently fall away either never had true faith to begin with or will return.
