I have not decided. I go back and forth
Supralapsarianism
First, the supralapsarian scheme. According to this view, God in order to manifest his grace and justice selected from creatable men (i.e., from men to be created) a certain number to be vessels of mercy, and certain others to be vessels of wrath. In the order of thought, election and reprobation precede the purpose to create and to permit the fall. Creation is in order to redemption. God creates some to be saved, and others to be lost.
This scheme is called supralapsarian because it supposes that men as unfallen, or before the fall, are the objects of election to eternal life, and foreordination to eternal death. This view was introduced among a certain class of Augustinians even before the Reformation, but has not been generally received. Augustine himself, and after him the great body of those who adopt his system of doctrine, were, and are, infralapsarians. That is, they hold that it is from the mass of fallen men that some were elected to eternal life, and some for the just punishment of their sins, foreordained to eternal death. The position of Calvin himself as to this point has been disputed. As it was not in his day a special matter of discussion, certain passages may be quoted from his writings which favour the supralapsarian and other passages which favour the infralapsarian view. In the “Consensus Genevensis,” written by him, there is an explicit assertion of the infralapsarian doctrine. After saying that there was little benefit in speculating on the foreordination of the fall of man, he adds, “Quod ex damnata Adæ sobole Deus quos visum est eligit, quos vult reprobat, sicuti ad fidem exercendam longe aptior est, ita majore fructu tractatur.” In the “Formula Consensus Helvetica,” drawn up as the testimony of the Swiss churches in 1675, whose principal authors were Heidegger and Turrettin, there is a formal repudiation of the supralapsarian view. In the Synod of Dort, which embraced delegates from all the Reformed churches on the Continent and in Great Britain, a large majority of the members were infralapsarians, Gomarus and Voetius being the prominent advocates of the opposite view. The canons of that synod, while avoiding any extreme statements, were so framed as to give a symbolical authority to the infralapsarian doctrine. They say: “Cum omnes homines in Adamo peccaverint et rei sint facti maledictionis et mortis æternæ, Deus nemini fecisset injuriam, si universum genus humanum in peccato et maledictione relinquere, ac propter peccatum damnare voluisset.” The same remark applies to the Westminster Assembly. Twiss, the Prolocutor of that venerable body, was a zealous supralapsarian; the great majority of its members, however, were on the other side. The symbols of that Assembly, while they clearly imply the infralapsarian view, were yet so framed as to avoid offence to those who adopted the supralapsarian theory. In the “Westminster Confession,” it is said that God appointed the elect unto eternal life, and “the rest of mankind, God was pleased, according to the unsearchable counsel of his own will, whereby He extendeth or withholdeth mercy as He pleaseth, for the glory of his sovereign power over his creatures, to pass by, and to ordain them to dishonour and wrath for their sin, to the praise of his glorious justice.” It is here taught that those whom God passes by are “the rest of mankind;” not the rest of ideal or possible men, but the rest of those human beings who constitute mankind, or the human race. In the second place, the passage quoted teaches that the non-elect are passed by and ordained to wrath “for their sin.” This implies that they were contemplated as sinful before this foreordination to judgment. The infralapsarian view is still more obviously assumed in the answers to the 19th and 20th questions in the “Shorter Catechism.” It is there taught that all mankind by the fall lost communion with God, and are under his wrath and curse, and that God out of his mere good pleasure elected some (some of those under his wrath and curse), unto everlasting life. Such has been the doctrine of the great body of Augustinians from the time of Augustine to the present day.
