Then the mother of the sons of Zebedee came up to him with her sons, and kneeling before him she asked him for something. And he said to her, “What do you want?” She said to him, “Say that these two sons of mine are to sit, one at your right hand and one at your left, in your kingdom.” Jesus answered, “You do not know what you are asking. Are you able to drink the cup that I am to drink?” They said to him, “We are able.” He said to them, “You will drink my cup, but to sit at my right hand and at my left is not mine to grant, but it is for those for whom it has been prepared by my Father.”
(Matthew 20:20-23 ESV)
Based on the above words of Jesus, Trinity fails when it claims the Father and Son are Co-Equal. Jesus clearly denies a trinity. Jesus had authority from God but not complete authority with respect to certain aspects of the kingdom proving the superiority of the Father over the son:
but to sit at my right hand and at my left is not mine to grant, but it is for those for whom it has been prepared by my Father
We need to look at all passages and reconcile them to ensure they are all speaking the same thing before we can conclude on a doctrine. It would be good to discover the truth together than to have men murdered in the name of doctrine and purity!
