Christ will therefore subject to himself everything [the universe], and this saving subjection it is right to regard as similar to that, according to which the Son himself shall be subjected unto him, who subjected to himself all things. . . . But after the close of everything, he will not dwell in a few, but in all those who are then worthy of the kingdom of heaven. So then shall come to pass [God’s being] all in all, when he inhabits as his people all [absolutely].
