THIS is about as official as it gets for people following the Reformist tradition.
Rev. Dr. Billy Graham wrote:
The Bible shows very clearly that there is only one God, and yet that there are three personal distinctions in His complex nature, traditionally referred to as “three Persons in the Godhead” -- God the Father, God the Son, and God the Holy Spirit.
Each is distinct from the others but never acts independently. They are one in nature and purpose. This mystery is called the doctrine of the Trinity, though that term is not used in the Bible. The teaching, however, is present in seed form in the Old Testament and is revealed explicitly in the New Testament. Note passages such as Matthew 28:19; John 10:30, 14:26; and 2 Corinthians 13:14.
In my personal interpretation, the Father is God's soul, the Son is God's physical body, and the Holy Spirit is God's personality.
Your interpretations may differ.
