What is the name of lucifers son?

Answer 1

The Bible does not say that Lucifer (aka Satan) has a son. His name means 'light-bringer' or 'bright and shining one', and in Isaiah 14:12 where he is called 'son of the morning' this is a pun where he is compared with the bright and shining planet Venus:-

Isa 14:12 [King James] 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!

However, when the Pharisees refused to believe Jesus was from God and was their Messiah He said their father was Satan the devil:-

Joh 8:44 Ye [ie these Pharisees] are of your father the devil [ie Lucifer/Satan], and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.

In that respect anyone who denies that Jesus is the Christ is a son of Lucifer.

1Jo 2:22 Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.

2Jo 1:7 For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.
