New American Bible John 1: 1-6
1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 He was in the beginning with God.
3 All things came to be through him, and without him nothing came to be. What came to be
4 through him was life, and this life was the light of the human race;
5 the light shines in the darkness, and the darkness has not overcome it.
form the Gospel we see that in the beginning was God and Jesus. and through Jesus God created all of creation.
NO thus Lucifer was yet just another creation of God through Jesus
As ST. Miachael is an Arch Angel and Adam was A human created form the clay of the earth they are separate creations. Satan was the Angel Lucifer. Not a son as you imply, but are all creation comes from God. in the very broadest terms all of creation is God children this.
What more do I need to draw upon to know the love Christ had for us than his Passion and Crusifiction.
