This graphic helps you understand in your mind what Christians believe teach and confess about the Trinity as the Bible reveals it.  You read the picture above like this:  “The Father Is God.” “The Son Is God.” “The Holy Spirit Is God.”  BUT  “The Father Is Not The Son And Is Not The Holy Spirit.”  “The Holy Spirit Is Not The Father And Is Not The Son” “The Son Is Not The Father And Is Not The Holy Spirit.”  Here you have the relationship depicted that the three Persons of the Trinity, Father Son and Holy Spirit, are unique and distinct, but all three are God… not three gods, but one God.
