What you don’t trust me?
(Greek, apokatastasis; Latin, restitutio in pristinum statum, restoration to the original condition).
A name given in the history of theology to the doctrine which teaches that a time will come when all free creatures will share in the grace of salvation; in a special way, the devils and lost souls.
This doctrine was explicitly taught by St. Gregory of Nyssa, and in more than one passage.
Catholic Encyclopedia
“In love did He bring the world into existence; in love does He guide it during this its temporal existence; in love is He going to bring it to that wondrous transformed state, and in love will the world be swallowed up in the great mystery of Him who has performed all these things; in love will the whole course of the governance of creation be finally comprised. And since in the New World the Creator’s love rules over all rational nature, the wonder at His mysteries that will be revealed then will captivate to itself the intellect of all rational beings whom He has created so that they might have delight in Him, whether they be evil or whether they be just.”
