Theophylact of Ohrid, on Heb 12:27

“And in that he saith, Yet once more, he signifieth the translation of the moveable things as made, that those things may remain which are immoveable.”

“That is, the change of corruptible creation, which by its very nature is capable of wavering; since it was created, that is, received a beginning of existence, it undoubtedly also has an end. For everything created received a beginning, and therefore, by its very nature, also has an end. And the angels are not infinite by nature; but they received immortality by divine grace. "That which is unshakeable may remain." That is, the future blessings. For when everything corruptible is changed, then all that is appointed for the righteous will be incorruptible and unshakable, subject to no "shaking" or change.”
