"I have not written unto you because ye know not the truth,but because ye know it,and that no lie is of the truth.
Who is a liar but he that denieth that Jesus is the Christ?He is antichrist,that denieth the Father and the Son.
Whosoever denieth the Son,the same hath not the Father:he that acknowledgeth the Son hath the Father also."
1 John 2:21-23
