Christ is the Only-Begotten, (not made) Son of God. Angels, including Satan, are created beings, as are we. Jesus is THE Son, The ONLY BEGOTTEN Son of God. The very reason the Jews sought to kill him was for the "blasphemy" of calling himself the Son of God--making him EQUAL with God:
John 5
18Therefore the Jews sought the more to kill him, because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God.
Philippians 2:6
Who, being in the form of God, thought it not robbery to be equal with God:
John 5 (cont.)
21For as the Father raiseth up the dead, and quickeneth them; even so
the Son quickeneth whom he will.
22For the Father judgeth no man, but
hath committed all judgment unto the Son:
23That all men should honour the Son, even as they honour the Father. He that honoureth not the Son honoureth not the Father which hath sent him.
24Verily, verily, I say unto you, He that heareth
my word, and believeth on him
that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.
25Verily, verily, I say unto you, The hour is coming, and now is, when
the dead shall hear the voice of the Son of God: and they that hear shall live.
26For as the Father hath life in himself;
so hath he given to the Son to have life in himself;
27And hath given him
authority to execute judgment also, because he is the Son of man.
28Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear
his voice, 29And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
John 20:28
And Thomas answered and said unto him, My LORD and my God.
