A Defense of Calvinism as the Gospel
To answer the O.P., Calvinism's TULIP system is often presented as the gospel itself, but when compared carefully with the words of Jesus, many of its central claims conflict with what Christ taught. The gospel of Christ repeatedly calls all people to repent, believe, obey, endure, and choose life. TULIP replaces much of that with a system where the outcome is fixed beforehand for each individual.
T - Total Depravity
Calvinism teaches that man is so fallen that he cannot respond to God unless first regenerated.
The Bible certainly teaches that man is sinful, but Jesus continually treated people as capable of responding to God's call.
Come unto me, all ye that labour and are heavy laden, and I will give you rest. (Matthew 11:28, ASV)
A command to come assumes the hearer can respond.
And ye will not come to me, that ye may have life. (John 5:40, ASV)
Jesus did not say they could not come. He said they would not come.
In the Old Testament God repeatedly calls people to choose:
I have set before thee life and death, the blessing and the curse: therefore choose life. (Deuteronomy 30:19, ASV)
A person who is incapable of responding cannot meaningfully be commanded to choose.
U - Unconditional Election
Calvinism teaches that before creation God chose certain individuals for salvation and passed over the rest regardless of anything they would do.
Jesus taught that God's desire extends to all.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth on him should not perish, but have eternal life. (John 3:16, ASV)
The invitation is to "whosoever."
Jesus also lamented over those who refused Him:
How often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not! (Matthew 23:37, ASV)
Christ desired one thing; they chose another.
If individuals were eternally decreed to reject Him, Christ's lament becomes difficult to explain.
L - Limited Atonement
Calvinism teaches that Christ died only for the elect.
Jesus taught a much broader message;
For the bread of God is that which cometh down out of heaven, and giveth life unto the world. (John 6:33, ASV)
And I, if I be lifted up from the earth, will draw all men unto myself. (John 12:32, ASV)
John wrote:
And he is the propitiation for our sins; and not for ours only, but also for the whole world. (1 John 2:2, ASV)
The language repeatedly points outward to the world, not merely a hidden group chosen beforehand.
I - Irresistible Grace
Calvinism teaches that when God decides to save someone, that person cannot finally resist His saving grace.
Yet Jesus frequently describes people resisting God.
Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Spirit. (Acts 7:51, ASV)
Jesus said:
And ye will not come to me, that ye may have life. (John 5:40, ASV)
And in the parable of the wedding feast many invited guests refused the invitation. God calls. Man can resist. Otherwise the repeated warnings against refusing, rejecting, hardening the heart, and neglecting salvation become meaningless.
P - Perseverance of the Saints
Calvinism teaches that every truly saved person will inevitably persevere to the end.
Jesus taught the necessity of continuing faithfully.
If ye abide in my word, then are ye truly my disciples. (John 8:31, ASV)
He that endureth to the end, the same shall be saved. (Matthew 24:13, ASV)
Notice the condition: "if" and "endure."
Jesus repeatedly warned believers about falling away.
In the parable of the sower, some receive the word with joy and later fall away.
And those on the rock are they who, when they have heard, receive the word with joy; and these have no root, who for a while believe, and in time of temptation fall away. (Luke 8:13, ASV)
A person who never truly believed cannot be described as one who "for a while believe."
The Deeper Problem
The deepest error of TULIP is that
it shifts the focus away from the relationship Jesus preached.
Jesus constantly calls people to:
Repent. (Matthew 4:17)
Believe the gospel. (Mark 1:15)
Follow me. (Matthew 4:19)
Keep my commandments. (John 14:15)
Abide in me. (John 15:4)
Endure unto the end. (Matthew 24:13)
The gospel of Christ is a genuine invitation to all people. God loves the world, calls the world, warns the world, and judges people according to their response to His Son.
Under TULIP, many of these invitations become difficult to take at face value. If people cannot respond, why call them? If Christ did not die for all, why offer salvation to all? If grace cannot be resisted, why warn against resisting? If salvation cannot be abandoned, why so many warnings about falling away?
The gospel preached by Jesus is simple: God calls, man must respond. God offers mercy, man must repent and believe. God gives grace, man must continue in faithfulness.
Enter ye in by the narrow gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many are they that enter in thereby. For narrow is the gate, and straitened the way, that leadeth unto life, and few are they that find it. (Matthew 7:13-14, ASV)
Jesus spoke as though people truly can choose whether they will enter that gate or refuse it. That is fundamentally different from the deterministic framework of TULIP.
