If you are born again in Christ you are not a Christian you are a son of God

1 Jn 5:12-13

12 He who has the Son has life; he who does not have the Son of God does not have life.

13 These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life,fn and that you may continue to believe in the name of the Son of God.
