What is double predestination?
http://www.gotquestions.org/double-predestination.html"Answer: Double predestination is the belief that God creates some people whose purpose in existence is to be sent to hell"
http://www.newadvent.org/cathen/12376b.htmHeretical Predestinarianism received a new and vigorous impulse at the outbreak of the Reformation. Luther having denied the freedom of the will in sinful man as also freedom in the use of grace, logically placed the eternal destiny of the individual solely and entirely in the hands of God, who without any regard to merit or demerit metes out heaven or hell just as He pleases. Zwingli endeavoured to obviate the grave consequences that this principle necessarily produces in the moral order by the vain excuse that "just as God incited the robber to commit murder, so also He forces the judge to impose the penalty of death on the murderer" (De provid. Dei, in "Opera" ed. Schuler, IV, 113). Melanchthon taught expressly that the treason of Judas was just as much the work of God as was the vocation of St. Paul (cf. Trident., Sess. VI, can. vi, in Denzinger, n. 816). Calvin is the most logical advocate of Predestinarianism pure and simple. Absolute and positive predestination of the elect for eternal life, as well as of the reprobate for hell and for sin, is one of the chief elements of his whole doctrinal system and is closely connected with the all-pervading thought of "the glory of God". Strongly religious by nature and with an instinct for systematizing, but also with a harsh unyielding character, Calvin was the first to weave the scattered threads which he thought he had found in St. Paul, St. Augustine, Wyclif, Luther, and Bucer, into a strong network which enveloped his entire system of practical and theoretical Christianity. Thus he became in fact the systematizer of the dread doctrine of predestination. Although Calvin does not deny that man had free will in paradise, still he traces back the fall of Adam to an absolute and positive decree of God (Instit., I, 15, 8; III, 23, 8).
Original sin completely destroyed the freedom of will in fallen man; nevertheless, it is not the motive of the decretum horribile, as he himself calls the decree or reprobation. Calvin is an uncompromising Supralapsarian. God for His own glorification, and without any regard to original sin, has created some as "vessels of mercy", others as "vessels of wrath". Those created for hell He has also predestined for sin, and whatever faith and righteousness they may exhibit are at most only apparent, since all graces and means of salvation are efficacious only in those predestined for heaven. The Jansenistic doctrine on redemption and grace in its principal features is not essentially different from Calvinism. The unbearable harshness and cruelty of this system led to a reaction among the better-minded Calvinists, who dreaded setting the "glory of God" above his sanctity. Even on so strictly Calvinistic a soil as Holland, Infralapsarianism, i.e. the connexion of reprobation with original sin, gained ground. England also refused to adhere to the strictly Calvinistic Lambeth Articles (1595), although in later years their essential features were embodied in the famous Westminster Confession of 1647 which was so strenuously defended by the English Puritans. On the other hand the Presbyterian Church in the United States has endeavoured to mitigate the undeniable harshness of Calvinism in its revision of its Confession in May, 1903, in which it also emphasizes the universality of the Divine love and even does not deny the salvation of children who die in infancy.
Comment-have seen Calvinists that state only they go to Heaven, Catholics automatically go to Hell......no matter ignorance, deceit,etc taught to them, Catholic= hellbound....no grace and mercy of God considered....
