“That people might receive the sacrament and the sacrament may work to their damnation we see right from the Holy Scripture, 1 Cor. 11:29.
Predestination has nothing to do with it.”
Predestination has everything to do with it, because it takes away the worth or unworthiness of the individual who eats or drinks and places it on the sovereign will of God who makes a man worthy or leaves Him to be unworthy.
This predestination IS the plan of God to give His grace to those who do not deserve it. What you must do is break away from the Catholic definition, which speaks of so many graces as if it were an inanimate object to be dispensed and then either lost or found by those fortunate enough to go through physical gestures or to chew with their teeth or be sprinkled as a child when they did not even believe (and the scriptures say, one must BELIEVE and be baptized, and those who BELIEVE not are damned. Why then is belief taken out of the equation altogether by the Catholics?). Salvation either belongs in the hand of God, or it belongs in the hand of men, it cannot be both, and the scripture testifies of the former.
True enough, but you (speaking collectively of anyone) don't know it. Whatever your predestination is, your works of faith are included in it, and so are the sacraments you receive -- or the sacraments you flee.

Grace is uncreated so not properly an "object". Read the Fathers of the Church with this in mind, and you will understand them better. It takes practice and study.
