TULIP is a popular acronym for the 5 points of Calvinism given in studied reply to the 5 points of the Arminianists by the Synod of Dort. “T” stands for Total Depravity, “U” stands for Unconditional Election, “L” stands for Limited Atonement, “I” stands for Irresistible Grace, “P” stands for Perseverance of the saints. Dr. Spencer’s Book “Tulip”, published by Baker Book House of Grand Rapids, is an outgrowth of these lectures.
