In theology, apocatastasis (/æpoʊkəˈtæstəsɪs/; occasionally spelled apokatastasis) is the restoration of creation to a condition of perfection. In Christianity, it is a form of Christian universalism that includes the ultimate salvation of everyone—including the damned in hell and the devil. The New Testament (Acts 3:21) refers to the "apocatastasis of all things", although this passage is not usually understood to teach universal salvation.
