The Trinity – One God in Three Persons
Question 6: Is there more than One True God?
Answer: No, there is only one true God. He eternally exists as the Trinity, one God in Three Persons – the Father, Son, and Holy Spirit. The Father, Son, and Spirit are distinct Persons, but are one in being, power, and glory.
