The Triune God is all over Scripture
All of creation is trinitarian, yet all of creation isn't God.
1-Salvation is Assigned by the Father
2-Salvation is Achieved through the Son
3-Salvation is Active from the Holy Spirit
1 Cor.8:6 points out that the Father is God while the Son is Christ. The Father is the origin of all creation while the Son is the means by which everything comes into being. The Father and Son are clearly distinguished.
We naturally assume that the means by which everything comes into being must be God, yet Paul never makes that claim. We're just begging the question. We're just assuming what we want to prove.
For all practical intents and purposes, there is only one way to worship God which would be to worship his image which is Christ. It doesn't then follow that Christ is God anymore than it would follow that the image you see in the mirror is you.
Paul points out that Christ is "the image (Greek "eikon") on the invisible god". An icon is not God, yet if one must objectively worship God, then the only option left to them is to worship the icon.
It is important to note that an icon is not necessarily synonymous with an idol. This is especially the case with the biblical God's prohibition against idolatry. An idol is worshipped as if it were God while an icon is a representation or representative.; and a representation is never what it represents. A representative is never who they represent.
Some examples of the trinity in reality are polarity which consists of two poles, yet they are one thing, i.e. polarity. The two poles have a relationship. The power that emanates from them is equivalent to the spirit. You cannot have one pole without the other. There is no such thing as just a north pole or positive pole without the corresponding south or negative pole.
Another example would be communication which consists of one who communicates and one to whom the message is communicated. This is a process known as communication. There can be no communication if there is no one to communicate to. So we're talking about one thing, i.e. communication, but this process requires the one communicating, the one to whom the message is communicated and the message itself.
Another example would be transportation which consists of a means of transportation as well as what or whom is being transported. It is one yet consists of three components; a trinity.
All of creation is trinitarian, yet nothing created is God, but necessarily comes from God.
