Traditional Calvinists believe in the doctrine of the perseverance of the saints, which says that because God chose some unto salvation and actually paid for their particular sins, he keeps them from apostasy and that those who do apostatize were never truly regenerated (that is, born again) or saved. Non-traditional Calvinists and other evangelicals advocate the similar but distinct doctrine of eternal security that teaches if a person was once saved, his or her salvation can never be in jeopardy, even if the person completely apostatizes.
