Calvinism, named for John Calvin (1509-1564), a French theologian active at Geneva, also referred to as Reformed Protestantism, out of which originated Congregationalism, Presbyterianism, &c. One of the founding branches of Protestantism, distinguished from the earlier Lutheranism doctrines by adherence to theories regarding the pneumatic presence of the Lord's Supper.
TULIP is an acrostic acronym that acts as a mnemonic for the essential tenets of Calvinism:
- Total depravity (all humans are born slaves to sin and are unable to change through their own actions)
- Unconditional election (God has chosen the Elect, those who are saved, and this decision is irrevocable)
- Limited atonement (Only the sins of the Elect have been redeemed by the sacrifice of Christ)
- Irresistible grace (the Elect are unable to resist the call to God's redemption)
- Perseverance of the Saints (the Elect will always remain so and cannot be made otherwise)
