The trinity makes no sense. Someone wise once said something like this, "The trinity is not found within the Bible. You cannot convince me that I am my father's son, and my father has a son, and I am also my father, and my father is his son" - Something like that. It makes no sense, it's not found within scripture. It can be assumed into scripture, but it is not within it. As scripture saith, there are Three that bear record in Heaven. The Father (1), The Word (2) and the Holy Ghost (3). And they all agree in one. And as scripture says, Jesus is one with the Father, but we also are to be one with God, so it doesn't mean that they are literally one. When looking "line upon line, precept upon precept" we see that the Trinity is a falsehood.
John 17:21-23 - That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. And the glory which thou gavest me I have given them; that they may be one, even as we are one: I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
Let's stop and think for a moment. Jesus wants us all to be one, just as his Father is in Him, and He is in His Father. Can you please tell me, how human beings are going to be literally one? It that possible? No. But we can be one in agreement, and one in accord. Because the Father is in Jesus, does this make Jesus the Father? If that was the case, then that would make us Jesus, because Jesus declares that he will be one in us. And Jesus wants us one in Him and His Father. I'm sorry, but how much plainer can His speech be? He doesn't mean literally one, and never has he meant that he has meant literally one.
"Yeah but, Jesus said if you've seen him, you've seen the Father"
Yes, He did. But if we stop again for a moment, he explains this perfectly within the same chapter. This doesn't mean they're literally one. He manifested His Father's name (character) to the world. Which is why, when you look at Jesus, you can see His Father.
John 17:6 - I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word.
If you have seen Jesus, who manifested His Father perfectly, and kept His Father's Commandments, you have seen the Father. It's just like a Christian. You haven't literally seen Jesus if you've seen a true Christian, but you've seen someone reflect Jesus to you.
Isaiah 28:9-10 - Whom shall he teach knowledge? and whom shall he make to understand doctrine? them that are weaned from the milk, and drawn from the breasts. For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little:
