According to Paul’s epistles, especially his epistle to the Ephesians, some were predestined before the universe was created to be adopted by God. This adoption would lead to the inheritance of the kingdom of God. This somewhat fatalist idea seems to go against important doctrines of the Church, such as free will. If one has the free decision to decide between good or evil, heaven or hell, then why does it even matter if one either has or hasn’t been already chosen to be saved? Does free will even exist?
God knew before the creation of the universe everything that would ever happen. He knew who would choose between the two paths of good and evil, and who would or wouldn’t be saved. He had a divine plan for the universe before its creation. This does not mean that people do not have the ability to decide between the two paths. There does exist a sort of predestination in God’s mind for every human ever to be created. Humans, however, can never know the divine plan of the universe, because it exists solely in the mind of God. It is self-glorifying to assume that it is possible for man to know what exists in the mind of God.
Paul’s epistle to the Ephesians does not go against any other doctrine of the Church. To say that it does would be to deny the omnipotence of God. Since the divine plan can never be known, we must strive to choose the good path, regardless of whether or not we have been predestined in the mind of God.
