The Mystery of Predestination: According to Scripture, the Church and St. Thomas Aquinas

How can an all loving God predestine some to eternal salvation while permitting others to fall away? Doesn't God offer the same amount of saving grace to everyone? Isn't predestination a Protestant doctrine? In The Mystery of Predestination, apologist and best-selling author John Salza (Why Catholic Cannot Be Masons) draws on Scripture, Tradition, and St. Thomas Aquinas' writings to uncover the fact that a proper Catholic understanding of predestination is interconnected with two other central mysteries: mankind's ability to choose freely to accept or reject God's saving Grace, and mankind's inability to accept that grace without first being moved by God from within.
