In Christian theology, the term for the final restoration of all creation at the end of time is apokatastasis.
Apokatastasis comes from a Greek word meaning restoration or reestablishment. In Christian theological history, it has been used especially for the idea that creation, and in some interpretations every rational creature, will ultimately be restored to harmony with God. The concept is linked by some theologians to biblical passages about the “restoration of all things.”
Origen of Alexandria is often associated with a strong form of the doctrine, although scholars debate exactly how he formulated it and how consistently later writers represented his views. Gregory of Nyssa and other Christian thinkers have also been discussed in relation to universal restoration, but their positions are not identical.
Apokatastasis is not the same as the general Christian belief in resurrection or the renewal of creation. It is a more specific theological proposal concerning the scope and outcome of divine restoration, and many Christian traditions reject universalist interpretations.
