It is a belief that the Father was the one who died in the cross and that the Father is the Son and the Son is the Father, all that happens to Jesus on earth was just a mere act of the script that was written before Jesus came.
They believe that the Son is just a phase or ministry or mode or a temporal office of the Father that happens only for 33 years. They don’t believe that there is a Son in heaven now at this very moment.
But the bible is very clear;
“Whoever believes in the Son has eternal life. Whoever doesn’t believe in the Son won’t see life, but the angry judgment of God remains on them.”John 3:36 CEB
The verse above does not restrict to believe that the Son only happens for 33 years. It goes before and beyond the 33 years when the Son was in the flesh.
Moreover, the bible is also very clear as below;
“Who is the liar? Isn’t it the person who denies that Jesus is the Christ? This person is the antichrist: the one who denies the Father and the Son. Everyone who denies the Son does not have the Father, but the one who confesses the Son has the Father also.” 1 John 2:22-23 CEB
Patripassianism denies the Son today since they don’t believe that there is a Son now in heaven. To them, the Son was just a phase and it ended in the cross. Their belief qualify to be an antichrist.
Truth be told, Son in the bible was defined to be the Image of the Invisible God.
“The Son is the image of the invisible God, the one who is first over all creation,” Colossians 1:15 CEB
An express or imprint of God’s being which is Spirit or, Life.
“The Son is the light of God’s glory and the imprint of God’s being. He maintains everything with his powerful message. After he carried out the cleansing of people from their sins, he sat down at the right side of the highest majesty.” Hebrews 1:3 CEB
The bible is clear that the Son or Image of God was already in the creation, in fact, we were created based on the Son or Image of God.
“God created humanity in God’s own image, in the divine image God created them, male and female God created them.” Genesis 1:27 CEB
God’s own Image is the Son and after the Son became Christ, the Image can be seen in heaven seating on the throne.
“At once I was in a Spirit-inspired trance and I saw a throne in heaven, and someone was seated on the throne.” Revelation 4:2 CEB
Therefore, one should never deny the Son or made it as if it’s simply an office or a phase, the Son is the Image of God, the firstborn over all creation. There will always be an image of God.
Father is THE ETERNAL LIFE. John 17:3
THE LIFE can be represented by the one who has it, if you represent THE LIFE accordingly, it will stay eternally with you even after physical death.
The begotten Son or the Image of God was the only one who reflected the Father in His exact essence hence, He inherited the most excellent name (Heb 1:4), His Father’s name which is Jesus.
