Many LDS apologists have pointed out that, absolutizing Col 1:16-20, one would have to argue that fallen angels and even Satan would be “reconciled.” On this, see the discussion of Col 1:15-20 in Refuting Jeff Durbin on “Mormonism”. Note the following from the late-17th/early-18th century Universalist George Klein Nicolai in his 1705 The Everlasting Gospel:
“For by him (Jesus Christ, the
only begotten Son of God) were all things created that are in heaven, and that
are in earth, visible and invisible, whether they be thrones, or dominions, or
principalities, or powers: all things were created by him and for him. And he
is before all things, and by him all things consist. And he is the head of the
body, the Church; who is the beginning, the first born from the dead; that in
all things he might have the pre-eminence. For it pleased the Father that in
him should all fulness dwell. And (having made peace through the blood of his
cross) by him to reconcile all things unto himself, by him, I say, whether they
be things in earth, or things in heaven.” (Col. 1:16-20)
This passage teaches us the extent
of the reconciliation made by Christ, namely, that it extends itself over the
whole creation. Therefore, the fallen angels must also necessarily have their
share in it, for they do incontestably belong to the invisible things created
by Christ, and consequently to all things, or the things in heaven reconciled
by him. And though it is true that through sin are separated from God,
nevertheless all the rest of the creatures partake of and are benefited by it.
It affords for instance, matter of much joy to the holy angels, when by virtue
of this reconciliation, the apostatized creatures are convened to God, and
thereby anew received into the communion and friendship of these holy spirits (Luke
13:10; 1 Pet. 1:12; Heb. 12:22). It will also be by the energy of this
reconciliation, that in time to come the curse which through sin was brought
upon the creation, and has mixed itself with it (Gen. 3:17; Rom. 8:20-22), will
be certainly removed from all the rest of the creatures. (George Klein Nicolai,
The Everlasting Gospel [Apophasis, 2018], 124-25)
