Thus the path of judgment for the elders during their lifetime was a trial of faith based on works under severe conditions and by it they received a more noble reward than their fellow man, being judged directly by God. The fallen spirits are just as their appellation states, spirits who had fallen. These actions look rather innocent. It is when we note the united testimony of the scriptures that we discern the truth of what really transpired here. In short, the heavenly host had no authorization to materialize as men, take women as wives and propagate.
Disobedience is sin irrespective of who does it.
However the path of judgment of the angels is manifestly different than for man, as represented in Adam. Adam was condemned to death, extinction, for his disobedience, whereas the angels did not receive as death sentence at that time. It was then that the final stage of their trial began. That thousand year day is here. The harvest of the Gospel age concludes the selection of the spirit-begotten ones as permanent members of the church, the Lamb's bride.
