Eternal security

Eternal security, also known as "once saved, always saved", is the belief that from the moment anyone becomes a Christian, they will be saved from hell, and will not lose salvation. Once a person is truly "born of God" or "regenerated" by the indwelling of the Holy Spirit, nothing in heaven or earth "shall be able to separate (them) from the love of God" (Romans 8:39) and thus nothing can reverse the condition of having become a Christian.

Eternal security is a characteristic doctrine of the Southern Baptists, Old Regular Baptists, United Baptists, Landmark Baptists, Missionary Baptists and other historic Baptist traditions. It is also held by various Calvinist groups such as Reformed Christians (Continental Reformed, Congregationalists, Presbyterians, Reformed Anglicans, and Reformed Baptists) due to the doctrine of Perseverance of the saints. It is also affirmed by the Plymouth Brethren, by the "Hyper-Grace" movement in Charismaticism as well as in Free Grace Theology, which is held by many independent fundamental Baptists and by a minority in many other denominations (though the Reformed, Plymouth Brethren, Hyper-Grace and Free Grace traditions teach different versions of eternal security). In contrast, conditional security is taught in Catholicism, Lutheranism, Orthodoxy, Pentecostalism and Methodism, as well as some Baptist groups such as the Freewill Baptists, General Baptists and Campbellites. The doctrine of the Anabaptists at the commencement of the Protestant Reformation was eternal security (as witnessed by the Lutheran diet of Augsburg in 1530), though most of the groups currently identified as Anabaptists, such as the Mennonites and Hutterites, embrace the conditional security doctrine.
