1 Corinthians 15:20-28
New American Standard Bible
The Order of Resurrection
20 But the fact is, Christ has been raised from the dead, the first fruits of those who are asleep. 21 For since by a man death came, by a man also came the resurrection of the dead. 22 For as in Adam all die, so also in Christ all will be made alive. 23 But each in his own order: Christ the first fruits, after that those who are Christ’s at His coming, 24 then comes the end, when He hands over the kingdom to our God and Father, when He has abolished all rule and all authority and power. 25 For He must reign until He has put all His enemies under His feet. 26 The last enemy that will be abolished is death. 27 For He has put all things in subjection under His feet. But when He says, “All things are put in subjection,” it is clear that this excludes the Father who put all things in subjection to Him. 28 When all things are subjected to Him, then the Son Himself will also be subjected to the One who subjected all things to Him, so that God may be all in all.
For me I feel like these verses often pose a problem for the typical Trinity belief because in it a paul writes that at some point in time Jesus will make every subject to him, and this won’t include God our father. Then Jesus will subject himself to God. So God the father will be over everything, including his son.
John 10:28-30 is often used as well here Jesus says the father and I are one. But right before that Jesus says none is greater than his father.
As for being one, the Bible says the same about us and Christ.
John 17 says
20 “I am not asking on behalf of these alone, but also for those who believe in Me through their word, 21 that they may all be one; just as You, Father, are in Me and I in You, that they also may be in Us, so that the world may believe that You sent Me.
So I believe that Jesus came to realize that he was the power of God made flesh, but I have a hard time seeing where Jesus says he is equal to God.
It makes me think of how in mythology the blood of Zeus hits the ground and became Athena. She was made of him but not equal to him.
