I asked something similar in another post, but didn’t want to overcrowd it since this technically is a different question.
I understand now that Calvinism is not a denomination but a belief system. So my question is, is the Calvinist belief system, the only Christian belief system that denies free will? If not, what are the other(s)?
Lutherans aren't Calvinists, like at all, but there are some ideas Lutherans and Calvinists share in common, though sometimes only superficially. One of these is that both Calvinists and Lutherans deny the freedom of the will.
Lutherans believe that, on account of sin, the human will is also sinful--and thus not free. Specifically, a human being cannot, by their own strength and power, be righteous. We cannot even come to God and say "yes" to Him.
Lutherans, like Calvinists, also believe in Predestination. However, we believe in it in a very different way than Calvinists do.
Calvinism holds that God has predestined some for election and salvation, and (at least by implication) either has selected the rest for damnation or has otherwise simply passed them over. From this, then, Calvinism (at least Five-Point Calvinism) argues that Christ only died for the elect (Limited Atonement), that the elect when they hear the Gospel will believe (Irresistible Grace) and can never fall away (Perseverance of the Saints).
Lutherans, on the other hand, maintain that predestination applies only to election. And it has nothing to do with God, in the beginning, picking and choosing who will or will not be saved. But rather, it means that God has chosen
you in Christ. How can you know this? Because God reveals it in Word and Sacrament. So you can know that you are predestined because you were baptized. Because you have heard the Gospel preached and you believe it. Because the words are spoken to you in the Sacrament of Absolution that your sins are forgiven on Christ's account. Election isn't secret, with only God knowing who is and isn't "really saved" or "truly elect". It is a public declaration through God's Means of Grace, for you, to you, that you are the object of God's love and affection in Christ. Christ, therefore, died for
everyone (Universal Atonement), we can resist and reject the call of the Gospel (Resistible Grace), and if we turn away from faith in Christ, we make shipwreck of our faith, and can become apostate and lost. So instead, Lutherans teach that the Christian can have full and complete confidence of their salvation in Christ, not by looking at themselves, but looking instead at the external word and promises of God, by looking to what God says and does: Christ died for you, you are baptized, here is Christ's Supper where you eat His flesh and drink His blood, the words of Absolution declare you forgiven; thus we teach the "Assurance of the Saints".
I'm offering terms like Universal Atonement, Resistible Grace, and Assurance of the Saints specifically as counter-terminoloy to the language of Calvinism's TULIP. Lutheranism doesn't have its own version of TULIP, but for the sake of comparison and contrast, this has been done.
Calvinism:
Total Depravity
Unconditional Election
Limited Atonement
Irresistible Grace
Perseverance of the Saints
Lutheranism's response to TULIP:
Total Inability (We are completely unable to be righteous and to come to God because of Original Sin)
Unconditional Election (God chooses us based entirely on His love and grace toward us in Christ, not because of anything worthy about us)
Universal Atonement (Jesus Christ died for the sins of the whole world, for everyone, completely, no exceptions)
Resistible Grace (We can resist and reject God's grace and forgiveness)
Assurance of the Saints (We can have full confidence and assurance of salvation because of God's faithful promises in the Gospel)
So, yes, there are others that deny the freedom of the will. Lutherans. But our denial of free will simply means that we are unable, by the power of our will, to be righteous--our will is held in bondage and captivity to sin.
If by "free will" one means can one make their own choices, then Lutherans believe in free will. In fact, we make those choices all the time, even in regard to God, we have a life-long record of our choosing
against God.
If by "free will" one means can one make a choice to be righteous and believe in Jesus Christ, then no, Lutherans don't believe in free will. Because, again, the fallen will actively chooses
against God.
