There are many ways of denying both the Father and the Son. One way is through the TRINITY doctrine and also the ONENESS doctrine which says that there is one PERSON that manifest in three offices of Father, Son and Holy Spirit. Many DENY the Father and Son by not really believing ELOHIM for the terms He used of FATHER and SON. They don’t believe in reality that there is REAL FATHER and REAL SON nor do they believe that the Father is GREATER than the Son. They think that ELOHIM DID NOT mean it when He chose to use the terms FATHER and SON. 1Jn 2:22 Who is the liar, except the one denying that יהושע is the Messiah? This is the anti-messiah, the one denying the Father and the Son. 1Jn 2:23 No one denying the Son has the Father. The one confessing the Son has the Father as well. POINTS TO NOTE 1. Denying the Father and the Son is like denying that the Messiah is not really the Son of ELOHIM but that He is 100% equal in EVERYTHING to the Father and indirectly saying that the Son is also the Father and that the Father is also the Son thereby taking these two terms as interchangeable. 2. Denying the Father and the Son is denying that the Father is Greater than the Son. 3. Denying the Father and the Son is denying that the Son is not as ALL-KNOWING as the Father. 4. Denying the Father and the Son is denying that the Father sends the Son and that the Son cannot send the Father. 5. Denying the Father and the Son is denying that the Son has to obey the Father and prayed to the Father but the Father does not need to pray to the Son. 6. Denying the Father and the Son is denying that the Father is overall and far above all and greater than all, including the Son. 7. Many are indirectly saying the Elohim is using Father and Son terms in VAIN to mean nothing. 8. Father and Son terms are used to carry divine TRUTHS about Elohim and He chose these earthly terms because we have fathers and sons on earth and we know what these terms mean on earth. Many ignore the DIVINE TRUTHS carried by the terms Father and Son. 9. Just like what earthly fathers and sons are on earth biologically, so are Father and Son in heaven are spiritually. 10. Just like earthly sons are required to obey their fathers and mothers so is the heavenly Son required to obey the heavenly Father. The Father is greater than the Son, and He is the HEAD of the Messiah (or Son). 11. Some completely and directly DENY the Father and the Son!
