According to the Trinity.
The Christian doctrine of the Trinity (from Latin trinitas "triad", from trinus "threefold")1 defines God as three consubstantial persons,2 expressions, or hypostases: the Father, the Son (Jesus Christ), and the Holy Spirit; "one God in three persons". The three persons are distinct, yet are one "substance, essence or nature". In this context, a "nature" is what one is, while a "person" is who one is.
According to this central mystery of most Christian faiths, there is only one God in three persons: while distinct from one another in their relations of origin (as the Fourth Lateran Council declared, "it is the Father who generates, the Son who is begotten, and the Holy Spirit who proceeds") and in their relations with one another, they are stated to be one in all else, co-equal, co-eternal and consubstantial, and "each is God, whole and entire".
Here is the question. In the article by John Frame, the Bible is the Word of God.
I believe that the God exists in three persons. But by the definition of John Frame, could we conclude that the God exists four persons, Father, Son, Spirit and the last one "Bible".
Am I misunderstanding John Frame's idea? Please read his paper first.
