T-U-L-I-P

A popularly recognized pneumatic representing the “pillars” of John Calvin’s teaching.

(aka “total inability”) Every person that is enslaved to sin as a result of the fall of man and further, is not inclined to love God. Instead, man’s nature is to reject the rule of God and serve themselves. As a result, no human has the moral capacity to choose to obey God for spiritual salvation. Their sin (“depravity”) affects every part of them (“total”). Calvin’s “total depravity” doctrine is based on his interpretation of Augustine’s definition of Original Sin.

From the beginning, God chose individuals that he would call his own. This was not based on any foreseen virtue, merit, or faith in those people. Instead, his selection is unconditional (e.g. unilateral) and based only on his mercy. He extends mercy and salvation in Christ Jesus to those chosen (the “elect”). Those not chosen are separated from him because of their sins, receiving his wrath.

(aka “particular redemption” or “definite atonement” or “particular atonement”) Because of God’s complete sovereignty over man, the sins of the elect – and only the elect – were atoned for by Jesus’ death.

(aka “efficacious grace”) God’s saving grace is effectually applied to those whom he has determined to save (that is, the elect). By his sovereignty, he overcomes any resistance to obeying the call of the gospel, bringing them to a saving faith. After all, he has purposed this from the beginning (“Unconditional election”). Here a distinction is made with the Holy Spirit’s “outward call” (preaching of the Gospel) that goes to all (elect and non-elect). It is only this “outward call” that can be rejected by sinners, whereas the “inward call” (or “effectual call”) of the Holy Spirit’s saving grace cannot be rejected (e.g “irresistible”).

(aka “perseverance of God with the saints” and “preservation of the believing”) God’s sovereignty precludes any that have received his “inward call” to be lost.  These “elect” will definitively be saved.
