The various branches within Christianity have different and often mixed views of predestination. I think the Calvinists were the only one who really focused on it and denied free will. And while it will likely bore most and be ignored, I thought the variations were rather fun....especially Double Predestination (just the name is great)
Conditional election
Conditional election is the belief that God chooses for eternal salvation those whom he foresees will have faith in Christ. This belief emphasizes the importance of a person's free will. The counter-view is known as unconditional election, and is the belief that God chooses whomever he will, based solely on his purposes and apart from an individual's free will. It has long been an issue in Calvinist–Arminian debate. An alternative viewpoint is Corporate election, which distinguishes God's election and predestination for corporate entities such as the community "in Christ," and individuals who can benefit from that community's election and predestination so long as they continue belonging to that community.
Supralapsarianism and infralapsarianism
Infralapsarianism (also called sublapsarianism) holds that predestination logically coincides with the preordination of Man's fall into sin. That is, God predestined sinful men for salvation. Therefore, according to this view, God is the ultimate cause, but not the proximate source or "author" of sin. Infralapsarians often emphasize a difference between God's decree (which is inviolable and inscrutable), and his revealed will (against which man is disobedient). Proponents also typically emphasize the grace and mercy of God toward all men, although teaching also that only some are predestined for salvation.
In common English parlance, the doctrine of predestination often has particular reference to the doctrines of Calvinism. The version of predestination espoused by John Calvin, after whom Calvinism is named, is sometimes referred to as "double predestination" because in it God predestines some people for salvation (i.e. unconditional election) and some for condemnation (i.e. Reprobation) which results by allowing the individual's own sins to condemn them. Calvin himself defines predestination as "the eternal decree of God, by which he determined with himself whatever he wished to happen with regard to every man. Not all are created on equal terms, but some are preordained to eternal life, others to eternal damnation; and, accordingly, as each has been created for one or other of these ends, we say that he has been predestined to life or to death."[79]
On the spectrum of beliefs concerning predestination, Calvinism is the strongest form among Christians. It teaches that God's predestining decision is based on the knowledge of his own will rather than foreknowledge, concerning every particular person and event; and, God continually acts with entire freedom, in order to bring about his will in completeness, but in such a way that the freedom of the creature is not violated, "but rather, established".[80]
Calvinists who hold the infralapsarian view of predestination usually prefer that term to "sublapsarianism," perhaps with the intent of blocking the inference that they believe predestination is on the basis of foreknowledge (sublapsarian meaning, assuming the fall into sin).[81] The different terminology has the benefit of distinguishing the Calvinist double predestination version of infralapsarianism from Lutheranism's view that predestination is a mystery, which forbids the unprofitable intrusion of prying minds since God only reveals partial knowledge to the human race.[citation needed]
Supralapsarianism is the doctrine that God's decree of predestination for salvation and reprobation logically precedes his preordination of the human race's fall into sin. That is, God decided to save, and to damn; he then determined the means by which that would be made possible. It is a matter of controversy whether or not Calvin himself held this view, but most scholars link him with the infralapsarian position. It is known, however, that Calvin's successor in Geneva, Theodore Beza, held to the supralapsarian view.
Double predestination
Further information: Predestination in Calvinism § Double predestination
Double predestination, or the double decree, is the doctrine that God actively reprobates, or decrees damnation of some, as well as salvation for those whom he has elected. Augustine made statements that on their own seem to teach such a doctrine, but in the context of his other writings it is not clear whether he held it. Augustine's doctrine of predestination does seem to imply a double predestinarian view.[28] Gottschalk of Orbais taught it more explicitly in the ninth century,[38] and Gregory of Rimini in the fourteenth.[82] During the Protestant Reformation John Calvin also held double predestinarian views.[83][84] John Calvin states: "By predestination we mean the eternal decree of God, by which he determined with himself whatever he wished to happen with regard to every man. All are not created on equal terms, but some are preordained to eternal life, others to eternal damnation; and, accordingly, as each has been created for one or other of these ends, we say that he has been predestinated to life or to death."[85]
Corporate election
Corporate election is a non-traditional Arminian view of election.[86] In corporate election, God does not choose which individuals he will save prior to creation, but rather God chooses the church as a whole. Or put differently, God chooses what type of individuals he will save. Another way the New Testament puts this is to say that God chose the church in Christ (Eph. 1:4). In other words, God chose from all eternity to save all those who would be found in Christ, by faith in God. This choosing is not primarily about salvation from eternal destruction either but is about God's chosen agency in the world. Thus individuals have full freedom in terms of whether they become members of the church or not.[86] Corporate election is thus consistent with the open view's position on God's omniscience, which states that God's foreknowledge does not determine the outcomes of individual free will.[citation needed]
Middle Knowledge
Middle Knowledge is a concept that was developed by Jesuit theologian Luis de Molina, and exists under a doctrine called Molinism. It attempts to deal with the topic of predestination by reconciling God's sovereign providence with the notion of libertarian free will. The concept of Middle Knowledge holds that God has a knowledge of true pre-volitional counterfactuals for all free creatures. That is, what any individual creature with a free will (e.g. a human) would do under any given circumstance. God's knowledge of counterfactuals is reasoned to occur logically prior to his divine creative decree (that is, prior to creation), and after his knowledge of necessary truths. Thus, Middle Knowledge holds that before the world was created, God knew what every existing creature capable of libertarian freedom (e.g. every individual human) would freely choose to do in all possible circumstances. It then holds that based on this information, God elected from a number of these possible worlds, the world most consistent with his ultimate will, which is the actual world that we live in.
For example:
if Free Creature A was to be placed in Circumstance B, God via his Middle Knowledge would know that Free Creature A will freely choose option Y over option Z.
if Free Creature A was to be placed in Circumstance C, God via his Middle Knowledge would know that Free Creature A will freely choose option Z over option Y.
Based on this Middle Knowledge, God has the ability to actualise the world in which A is placed in a circumstance that he freely chooses to do what is consistent with Gods ultimate will. If God determined that the world most suited to his purposes is a world in which A would freely choose Y instead of Z, God can actualise a world in which Free Creature A finds himself in Circumstance B.
In this way, Middle Knowledge is thought of by its proponents to be consistent with any theological doctrines that assert God as having divine providence and man having a libertarian freedom (e.g. Calvinism, Catholicism, Lutheranism), and to offer a potential solution to the concerns that God's providence somehow nullifies man from having true liberty in his choices.
