In the thread "
What is an Angel? What is the Difference?" I have argued that angels are mankind. Some are under the impression that Lucifer was an angel and not a man. I would argue that Lucifer was both. As one of the spirit children of God, He along with 1/3 of the hosts of heaven rebelled against God and were cast out of heaven. Angels are not a different species than man. An angel is nothing more than a messenger of God. Although Lucifer was a messenger of God (angel) he was also the offspring of God like all of Gods children. Isaiah 14 tells us that Lucifer is a man in spirit:
Isaiah 14:12-17
12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:
14 I will ascend above the heights of the clouds; I will be like the most High.
15 Yet thou shalt be brought down to hell, to the sides of the pit.
16 They that see thee shall narrowly look upon thee, and consider thee, saying, Is this the
man that made the earth to tremble, that did shake kingdoms;
17 That made the world as a wilderness, and destroyed the cities thereof; that opened not the house of his prisoners?
Here Isaiah tells us that Lucifer is a man.
