I believe the biblical Trinity is partialistic. This means that God consists of three different parts. An example of this is a triangle. It has three different corners that form one triangle. The three corners would be the three persons of the Trinity and together they are one God/triangle. Another example would be the color white. You need three different primary colors for the color white. The three primary colors would be the three persons of the Trinity and together they are God/white.That is similar to what I believe: #932
I believe that the Father, Son, and Holy Spirit are dependent on each other, although I do not believe that the Holy Spirit is a Person.
I believe the Holy Spirit is the Bounty of God (the Father) whose luminous rays emanated from Jesus, after God (the Father) sent the Holy Spirit to Jesus.
The Trinity also teaches subordination. But this subordination is NOT related to nature but only to the roles. An example of this is the human body. A human has one head and two arms. The head is the Father, the right arm is Jesus and the left arm is the Holy Spirit. In the hierarchy of roles, the Father is the first, the Son the second and the Holy Spirit the third. But in their nature they are the same!
As you can see, the biblical Trinity is partialistic, which means that the three persons are dependent on each other and are therefore only God together. They were never separate but were always together and will always be together. But the "mainstream" Trinity believed by Catholics says that the three persons are independent of each other. But then they cannot be one God! If the three persons are independent of each other then they are three different gods.
Furthermore, Catholics believe in the "Eternal Generation of the Son" which means that the Father begot the Son before the world. In other words, God has begotten another personal God. This is absolutely false and idolatry! The Son was only once begotten and that was at his human incarnation.
