From The Cruciform View:

The overall thrust of this chapter in Cary’s monograph is that Augustine’s idiosyncratic formulation of election and predestination (which would later influence Calvin and Luther’s own idiosyncratic neo-Augustinian versions of the doctrine) was influenced by Platonic and Neo-Platonic thought patterns of grace that differed significantly from the Pauline and Hebraic concept of grace, which is given to one (Israel, Christ, the Church) for the benefit of others rather than merely and arbitrarily given to one instead of another, which as Cary rightly says, leads logically to the “outright disaster” of Augustine’s (and later Calvin’s) doctrine of double-predestination.
