To be totally honest, The phrase “doctrines of grace” is used as a replacement for the term “Calvinism,” in order to remove the attention from John Calvin and instead focus on how the specific points are biblically and theologically sound.
Calvinistic teaching said that grace doctrines are summarized with the acronym TULIP.
T in TULIP stands for Total Depravity
U for Unconditional Election,
L for Limited Atonement,
I for Irresistible Grace, and
P for Perseverance of the Saints.
Reformed Christians believe that all five of the doctrines of grace are derived directly from the Scripture and that the acronym TULIP accurately describes the Bible’s teaching on soteriology—the doctrine of salvation which stems only from the GRACE of God.
