TULIP is an acronym that represents five core beliefs of Calvinism, a branch of Protestant Christianity. The five points are: Total Depravity, which suggests that all humans are inherently sinful; Unconditional Election, meaning that God chooses certain individuals for salvation; Limited Atonement, indicating that Christ's sacrifice was intended only for the elect; Irresistible Grace, which asserts that those chosen by God cannot resist His call; and Perseverance of the Saints, which states that the elect will remain faithful until the end. These principles were formulated in response to the Arminianism movement in the 17th century, which emphasized free will and the ability to choose salvation. TULIP serves as a summary of the theological differences between these two perspectives, shaping discussions on salvation and divine grace within the Christian faith.
