We now examine the third and final principles of the Trinity, which is this: the three persons of God are each fully God and are eternally distinct from each other. In other words, the Father is not the Son or the Spirit, nor is the Son the Spirit, but each is fully God and this has always been that way and will always be that way.
In the previous article we defined the doctrine of the Trinity in terms of three principles. Then we proceeded to show that the Bible clearly teaches the first principle of the Trinity: that there is one and only one God. Having established this, we now move on to ask if the second principle of the Trinity is biblical.
If we are to have a correct understanding of God, then we must accept what God has said about Himself. This is why the Trinity is an essential Christian doctrine. Many people deny what the Bible says about God’s nature, and instead place their faith in a god they have produced from their own imagination – a god that is easier to understand. The problem is, an imaginary god cannot save you. Only the real God can. And the real God is Triune.
