You guys are both wrong in your understanding.
Heb 1 :5-7 For unto which of the angels said He at any time, Thou art my Son, this day have I begotten thee? And again , I will be to him a Father, and He shall be to Me a Son? And again, when He bringeth in the first-begotteen into the world, He saith, " And let all the angels of God worship Him. And of the angels He saith , Who maketh His angels spirits, and His ministers a flame of fire.
Christ's existence emanated from the Father's essence from which all things exist. Christ is the first living spiritual being that came from the Father. That is why He is the Father's Son. Just like the Father, Christ has His own mind, heart, and soul. Because the Father's essence completely fills Christ's being, Christ, with His free will, chooses to love and obey Him. That is why He sits at the Father's right hand (to do the Father's will). The Father communicates His will to the Son through His essence. The Father and Son are One in that whatever the Father wants, the Son wants also. The Son's will might differ from the Father, but the Son gladly acquiesces to the will of the Father. When Christ became a man, the essence of God the Father, through which Mary's seed was fertilized, again resulted in Christ being born but this time as a human. The Father and Son relationship occurs a second time ( And again ).
God has always existed. He has no beginning and no end. He transcends time, is omnipotent, omnipresent, omniscient, and all-powerful. He can be described as an essence that permeates everywhere and possesses a mind, heart, and soul. Eph 4: 6 There is...One God and Father of all, who is above all, and through all, and in you all. In John 15: 26 and John 8: 42 the Holy Spirit and Christ proceedeth from the Father. The Holy Spirit is the Father's Spirit through which He communicates and empowers.
Isaiah 43: 10 ... before me there was no God formed, neither shall there be after me. This verse is spoken by Christ because the Father has no beginning but apparently, the God (Christ) in Isaiah 43: 10 had a time that existed before Him which means that He didn't always exist in the past. Actually, the beginning started when Christ was formed out of the Father's essence. Alpha and Omega means the first and the last.
The Father created all things through Christ, which makes Christ the Lord and God of all creation, but the Father is God of all.
Heb 1: 8 But unto the Son He saith, Thy throne, O God, is forever and ever; a scepter of righteousness is the scepter of thy kingdom.
The Father gives Christ a kingdom to rule forever, made up of righteous beings who worship Him as a God. Notice that the Father refers to His Son as " O God ".
Heb 1 : 9 Thou hast loved righteousness , and hated iniquity; therefore, God, even ( that is ) thy God, hath anointed Thee with the oil of gladness above thy fellows.
Jesus' God ( the Father) has anointed Jesus with the oil of gladness above all created beings because Jesus loves righteousness ( doing the Father's will) and hates iniquity ( disobeying His will).
