In The Mystery of Predestination, apologist John Salza (The Biblical Basis for Purgatory) answers questions about that most confounding to Christian beliefs: that God chooses to infallibly direct certain people to salvation but not others.
Drawing upon Scripture, Tradition, and the writings of St. Thomas Aquinas, Salza shows how man is unable to accept saving grace without first being moved by God from within; yet he is able to reject that grace all on his own. In this way we can see how God specially chooses, seeks, and saves his Elect, but never wills that anybody go to Hell.
Meticulously researched and written in an accessible style, The Mystery of Predestination is perfect for the serious Catholic who is confused by Bible verses or Calvinist arguments about predestination, and is seeking clear, traditional answers from the mind of St. Thomas.
