If you are into angelogy the one who sits at the right hand of the father is Michael. And at one point Lucifer sat at the father's left hand. There is no mention of Jesus sitting at either side of his father- typically in a monarchy the prince goes out of the castle and learns to become a king, conducting missions, while the father works from home- rarely leaving the capital or homeland. Furthermore when Jesus says that "I and the father are one" he is not saying that he is God nor that he is his own father- such an interpretation is rather strange and unusual- also very impossible. One cannot be one's father and son at the same time. But if you are clinging to such an interpretation Catholicism and Protestantism are right up your alley.
If you are trying to follow the teachings of the Christ I recommend Gnosis. When Christus states that he and his father are one, he is stating that he and his father work in coordination and synchronicity. Jesus never states that he is god- though one may presume he is a lot like a Hercules figure in so much that he is half immortal god and half mortal man. Which is why he understands the plight of those humans seeking salvation of the mind and spirit and to return to the Tree of Life.
I wish to remind all followers of Christ that the bible is an incomplete work as it does not tell of how Man shall return to the TOL except for vague mentionings of through prayers to the one known by the pseudonym Jesus Christ.
