 This new tension eventually became obvious with the confrontation between Augustine and Pelagius culminating in condemnation of Pelagianism (as interpreted by Augustine) at the Council of Ephesus in 431.Pelagius denied Augustine's view of predestination in order to affirm that salvation is achieved by an act of free will.The Council of Arles in the late fifth century condemned the position "that some have been condemned to death, others have been predestined to life", though this may seem to follow from Augustine's teaching.
