We have tried to decipher the Trinity from what the Bible says about God. In one place it says He is One God. In another Jesus says He is God and in another the Holy Spirit is God and in another we have God the Father and in Genesis He uses the plural when referring to Himself.
We have been through several ways to explain the One and the Three, but I’ve not seen any effort to describe the revelation of God from God’s point of view.
Consider this: God the Father, God the Son, God the Holy Spirit exist in Eternity. Their cooperation in the Creation is absolute. There is not one particle of difference in the Plan of God between them. The only difference is the role and purpose each assumes in fulfilling the plan. Every detail from one subatomic particle to the absolute ends of the universe is agreed upon. Every being, rock and tree, is here for a purpose in that plan. In the outworking of that purpose and in the unity of that purpose They are ONE! In their moral code and perfection of coordination of their revealed individual persons They are AS One. As Jesus said you have seen Me, you have seen My Father also.
The revelation of God to us in terms of absolute unity of final purpose for Creation teaches He is One. In terms of accomplishing those individual goals as revealed of His plan in time the Three Persons each have individual actions and activities.
We have ruled out modalism but cannot seem to wrap our heads around how three persons can be One God. If we conceive of God’s unity of purpose as binding the three persons together so perfectly that from our point of view He IS One in Three, what have we lost? What violence have we done to our understanding of the Trinity as three persons, One God? Need there be factionalism and discord over accepting such a simple understanding? After all, aren’t we dealing with a God who is capable of such perfect alignment of purpose between the Father, the Son, and the Holy Spirit that they are One?
