While we are called to humility in all things, the Church also invites the faithful to think on the various mysteries of God and try to express them; this is what we call development of doctrine.
Free will and predestination are part of these mysteries and while the Church allows certain schools of thought, she has not ruled definitively on the issue. Essentially, we are required to hold some principles and develop thought within these principles. These principles include:
*]God gives sufficient grace to every human being for his salvaton.
*]God gives each human being the free will to accept or reject that grace.
*]God ordains, from an eternal resolve of his will to predestine certain people to eternal blessedness (predestination to glory; a note on this one: the Church does not rule on whether this is in light of foreseen merits or without consideration of forseen merits)
*]God ordains, in light of foreseen demerits, certain people to eternal damnation (unlike the Calvinists, the Church holds that God does not predestine people to hell without consideraton of foreseen demerits; this is condemned as heretical and unscriptural).
*] The number of both the predestined and the reprobate are both unknown and immutable.
Because Scripture repeatedly exhorts people to come to God, as well as warns against turning away, there is clearly an expectation of free response there. But it’s just as clear that no one can turn to God without God’s initial movement; this is grace. So it is correct that no one can come to the Father unless he draw him, but that is not an opposition to free will. Rather, we believe that yes, unless the Father draws a man (i.e. be offered grace), he cannot respond. And the Father will draw men, but not all will respond. So the two are not mutually exclusive.
