"That the doctrine of the Reformed churches concerning predestination, and the points annexed to it, by its own genius and necessary tendency, leads off the minds of men from all piety and religion; that it is an opiate administered by the flesh and by the devil, and the stronghold of Satan, where he lies in wait for all; and from which he wounds multitudes, and mortally strikes through many with the darts both of despair and security; that it makes God the author of sin, unjust, tyrannical, hypocritical; that it is nothing more than interpolated Stoicism, Manicheism, Libertinism, Turcism; that it renders men carnally secure, since they are persuaded by it that nothing can hinder the salvation of the elect, let them live as they please; and therefore, that they may safely perpetrate every species of the most atrocious crimes; and that, if the reprobate should even perform truly all the works of the saints, their obedience would not in the least contribute to their salvation; that the same doctrine teaches, that God, by a mere arbitrary act of his will, without the least respect or view to sin, has predestinated the greatest part of the world to eternal damnation; and, has created them for this very purpose; that in the same manner in which the election is the fountain and cause of faith and good works, reprobation is the cause of unbelief and impiety; that many children of the faithful are torn, guiltless, from their mothers' breasts, and tyrannically plunged into hell; so that, neither baptism, nor the prayers of the Church at their baptism, can at all profit by them;" and many other things of the same kind, which the Reformed Churches not only do not acknowledge, but even detest with their whole soul.
