Confirmed: Gavin Ortlund has too small a mind to comprehend Origen.
"I am of opinion that the expression, by which God is said to be ‘all in all,’ means that He is all in each individual person. Now He will be all in each individual in this way: when all which any rational understanding, cleansed from the dregs of every sort of vice, and with every cloud of wickedness completely swept away, can either feel, or understand, or think, will be wholly God; and when it will no longer behold or retain anything else than God, but when God will be the measure and standard of all its movements; and thus God will be all, for there will no longer be any distinction of good and evil, seeing evil nowhere exists; for God is all things, and to Him no evil is near: nor will there be any longer a desire to eat from the tree of the knowledge of good and evil, on the part of him who is always in the possession of good, and to whom God is all."
So then, when the end has been restored to the beginning, and the termination of things compared with their commencement, that condition of things will be re-established in which rational nature was placed, when it had no need to eat of the tree of the knowledge of good and evil; so that when all feeling of wickedness has been removed, and the individual has been purified and cleansed, He who alone is the one good God becomes to him all, and that not in the case of a few individuals, or of a considerable number, but He Himself is all in all. And when death shall no longer anywhere exist, nor the sting of death, nor any evil at all, then verily God will be all in all."
