Scripture says both that God chose people before the foundation of the world and that whoever wills may come. It says salvation does not depend on human will or exertion, and it holds people responsible for refusing. Every position below is an attempt to hold those together.
This is the oldest live argument in Western Christianity, running from Augustine and Pelagius through the Reformation to the present. It is also the one most likely to be conducted badly, with each side attacking a version of the other that nobody actually holds.
Romans 9, Ephesians 1:3-14, John 6:37-44
3Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ, 4even as he chose us in him before the foundation of the world, that we would be holy and without defect before him in love, 5having predestined us for adoption as children through Jesus Christ to himself, according to the good pleasure of his desire, 6to the praise of the glory of his grace, by which he freely gave us favor in the Beloved.
All these views affirm that salvation is by , that no one is saved by their own , that God genuinely desires people to be saved, and that human beings are really responsible for their response. Nobody here believes people save themselves, and nobody here believes people are robots.
Reformed, or Calvinist
God chose a people before creation, not on the basis of anything foreseen in them, and effectively brings them to faith. Grace is the cause of faith, not its reward.
What it claims
Fallen humanity is unable to come to God unaided, so if anyone is saved, God must act first and decisively. He does, for those he has chosen, and that call is effective. Perseverance follows, because the one who began the work completes it.
Who holds it
and Reformed churches, confessional Baptists, many Anglicans, and a large part of the modern evangelical world. Set out in the of Dort and the Westminster , with Augustine as the older source.
The texts it stands on
Ephesians 1:4-5 He chose us in him before the foundation of the world, having predestined us for adoption.
John 6:44 No one can come to me unless the Father who sent me draws him.
Romans 9:16 So then it is not of him who wills, nor of him who runs, but of God who has mercy.
Strongest case
It gives the fullest weight to the passages about God's initiative and to the seriousness of human inability, and it grounds in God's action rather than in the strength of one's own faith.
Hardest question
If God could save everyone and chooses not to, the question of why is very hard, and the standard answers do not satisfy everyone. Critics also press whether a choice that cannot be otherwise is meaningfully a choice.
Holding the map
The best test of whether someone understands this argument is whether they can state the other side without a sneer. Reformed Christians are not fatalists and do evangelize; Arminians are not semi-Pelagians and do believe salvation is by grace alone. Both accusations get thrown, and both are usually false.
It is also worth noticing where the argument does not run. Every position here is inside historic Christianity, all of them are represented in churches that recite the same , and the disagreement has never been treated by most traditions as a test of whether someone is a Christian.
Questions that press on this one
None of these stands on its own. What you conclude here narrows what you can say there.
