I wrote this in another website, I hope that this is okay with the moderation as defined by the terms of service to quote it here.
The T.U.L.I.P is in my view the best summary of the Gospel and Biblical Christianity. Though the article is specifically about Reformed Christianity which I believe... is biblical Christianity in its truest and most consistent form.
Salvation by Grace. Reformed theology teaches that God in His grace and mercy has chosen to redeem a people to Himself, delivering them from sin and death. The Reformed doctrine of salvation is commonly represented by the acrostic TULIP (also known as the five points of Calvinism). Calvinism is a rare theology: It can be simply explained using a five-letter acronym. This set of religious principles is the work of John Calvin (1509-1564), a French church reformer who had a permanent influence on several branches of Protestantism. Like Martin Luther before him, John Calvin broke from the Roman Catholic Church and based his theology on the Bible alone, not the Bible and tradition. After Calvin's death, his followers spread those beliefs throughout Europe and the American colonies. The five points of Calvinism can be remembered using the acronym TULIP:
T - "Total depravity," also called "total inability," asserts that as a consequence of the fall of man into sin, every person is enslaved to sin. People are not by nature inclined to love God but rather to serve their own interests and to reject the rule of God. Thus, all people by their own faculties are morally unable to choose to follow God and be saved because they are unwilling to do so out of the necessity of their own natures. (The term "total" in this context refers to sin affecting every part of a person, not that every person is as evil as they could be). This doctrine is derived from Augustine's explanation of Original Sin. While the phrases "totally depraved" and "utterly perverse" were used by Calvin, what was meant was the inability to save oneself from sin rather than being absent of goodness. Phrases like "total depravity" cannot be found in the Canons of Dort, and the Canons as well as later Reformed orthodox theologians arguably offer a more moderate view of the nature of fallen humanity than Calvin.
Mark 7:20-23, "And He was saying, "That which proceeds out of the man, that is what defiles the man. 21 "For from within, out of the heart of men, proceed the evil thoughts, fornications, thefts, murders, adulteries, 22 deeds of coveting and wickedness, as well as deceit, sensuality, envy, slander, pride and foolishness. 23 "All these evil things proceed from within and defile the man." Matt. 7:17, "Even so, every good tree bears good fruit; but the bad tree bears bad fruit."
U - "Unconditional election" asserts that God has chosen from eternity those whom he will bring to himself not based on foreseen virtue, merit, or faith in those people; rather, his choice is unconditionally grounded in his mercy alone. God has chosen from eternity to extend mercy to those he has chosen and to withhold mercy from those not chosen. Those chosen receive salvation through Christ alone. Those not chosen receive the just wrath that is warranted for their sins against God.
John 6:44, "No one can come to Me, unless the Father who sent Me draws him; and I will raise him up on the last day." John 6:65, "And He was saying, "For this reason I have said to you, that no one can come to Me, unless it has been granted him from the Father." Mark 4:10-12, "And as soon as He was alone, His followers, along with the twelve, began asking Him about the parables. 11 And He was saying to them, "To you has been given the mystery of the kingdom of God; but those who are outside get everything in parables, 12 in order that while seeing, they may see and not perceive; and while hearing, they may hear and not understand lest they return and be forgiven." Matt. 11:27, "All things have been handed over to Me by My Father; and no one knows the Son, except the Father; nor does anyone know the Father, except the Son, and anyone to whom the Son wills to reveal Him." John 6:38-40, "For I have come down from heaven, not to do My own will, but the will of Him who sent Me. 39 “And this is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. 40 “For this is the will of My Father, that everyone who beholds the Son and believes in Him, may have eternal life; and I Myself will raise him up on the last day.”
L - "Limited atonement," also called "particular redemption" or "definite atonement", asserts that Jesus's substitutionary atonement was definite and certain in its purpose and in what it accomplished. This implies that only the sins of the elect were atoned for by Jesus's death. Calvinists do not believe, however, that the atonement is limited in its value or power, but rather that the atonement is limited in the sense that it is intended for some and not all. Some Calvinists have quipped, "The atonement is sufficient for all and efficient for the elect," while other Calvinists find such wording confusing rather than helpful. All Calvinists would affirm that the blood of Christ was sufficient to pay for every single human being IF it were God's intention to save every single human being. But Calvinists are also quick to point out that Jesus did not spill a drop of blood in vain (Galatians 2:21), and therefore, we can only be sure that His blood sufficed for those for whom it was intended, however many (Matthew 26:28) or few (Matthew 7:14) that may be. Some Calvinists also teach that the atonement accomplished certain benefits for all mankind, albeit, not their eternal salvation. The doctrine is driven by the Calvinistic concept of the sovereignty of God in salvation and their understanding of the nature of the atonement. At the Synod of Dort, both sides agreed that the atonement of Christ's death was sufficient to pay for all sin and that it was only efficacious for some (it only actually saved some). The controversy centered on whether this limited efficacy was based on God's election (the view of the Synod and of later Reformed theologians) or on the choice of each person and God's foreknowledge of that choice (the view of Arminius).
John 10:11, "I am the good shepherd; the good shepherd lays down His life for the sheep." John 10:26, "But you do not believe, because you are not of My sheep." Matt. 25:32, "And all the nations will be gathered before Him; and He will separate them from one another, as the shepherd separates the sheep from the goats; 33 and He will put the sheep on His right, and the goats on the left."
I - "Irresistible grace," also called "efficacious grace", asserts that the saving grace of God is effectually applied to those whom he has determined to save (that is, the elect) and overcomes their resistance to obeying the call of the gospel, bringing them to a saving faith. This means that when God sovereignly purposes to save someone, that individual certainly will be saved. The doctrine holds that this purposeful influence of God's Holy Spirit cannot be resisted, but that the Holy Spirit, "graciously causes the elect sinner to cooperate, to believe, to repent, to come freely and willingly to Christ." This is not to deny the fact that the Spirit’s outward call (through the proclamation of the Gospel) can be, and often is, rejected by sinners; rather, it’s that inward call which cannot be rejected. In fact, every saved person can testify how, at some point in their life, they “felt overwhelmingly compelled” to believe in Christ, as if they “had no choice but to follow Him.” This is what is meant by the effectual calling of God.
Matt. 4:19, "And He *said to them, "Follow Me, and I will make you fishers of men." 20 And they immediately left the nets, and followed Him." Matt. 9:9, "And as Jesus passed on from there, He saw a man, called Matthew, sitting in the tax office; and He *said to him, “Follow Me!” And he rose, and followed Him." John 6:37, "All that the Father gives Me shall come to Me, and the one who comes to Me I will certainly not cast out." John 6:65, "And He was saying, “For this reason I have said to you, that no one can come to Me, unless it has been granted him from the Father.”
P - "Perseverance of the saints" (or perseverance of God with the saints) (the word "saints" is used to refer to all who are set apart by God, and not of those who are exceptionally holy, canonized, or in heaven) asserts that since God is sovereign and his will cannot be frustrated by humans or anything else, those whom God has called into communion with himself will continue in faith until the end. Those who apparently fall away either never had true faith to begin with (1 John 2:19), or, if they are saved but not presently walking in the Spirit, they will be divinely chastened (Hebrews 12:5–11) and will repent (1 John 3:6–9).
John 6:38-40, "For I have come down from heaven, not to do My own will, but the will of Him who sent Me. 39 “And this is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. 40 “For this is the will of My Father, that everyone who beholds the Son and believes in Him, may have eternal life; and I Myself will raise him up on the last day.” John 6:66, "After this many of his disciples turned back and no longer walked with him." John 10:27-28, "My sheep hear My voice, and I know them, and they follow Me; 28 and I give eternal life to them, and they shall never perish; and no one shall snatch them out of My hand."
God bless,
