Predestination is primarily a Calvinist concept. It takes a Scripture passage or two (see Romans 8:29-30 and Ephesians 3-14) and weaves a theology of predestination around it. Catholics prefer to see Paul’s use of the term ‘predestination’ to refer to God’s foreknowledge of what a person will chose to do. God offers his grace to all, but because for God all of human history is equally present as a now, God knows what a person in his or her free will will chose. Thus God knows those who will accept his Son and live in him. As St. Paul says: “Those whom he foreknew he predestined to share the image of his Son…” (Romans 8:29). In Ephesians St. Paul sees the Christian community’s acceptance of the grace of Christ as being something that God foreknew, and uses it to begin “to bring all things in  heaven and on earth into one under Christ’s headship.” For more information, see The Catechism of  the Catholic Church on God’s Providence, #302-315.
