So is Jesus a person, a being and God by Himself or is He God only with the other two?
This may help explain what you mean by 'person' and 'being'.
if you had read the parts of my paper I posted, I clearly defined the differences between "being" or ousia and "person" or hypostasis.
God has one being or substance. That is his essence. The Father is a person, Jesus is a person, and the Holy Spirit is a person.
But:
The Father is NOT the Son
The Father is NOT the Holy Spirit.
The Son is NOT the Holy Spirit.
Acknowledge you me wrong use of the English words, "being" and "persons!" Admit they are completely different words, not the same definition. Then you will have a hope of understanding the Trinity.
As it stands now, you have acknowledged your confusion. Confess your erroneous use of the 2 words, and then we can help you understand that without a Triune God, you cannot be a. Christian, you cannot be saved or sanctified.
