God the Holy Spirit
Is there any scriptural evidence that says the Holy Spirit is a separate person from God the Father? What if the Holy Spirit is actually God the Father's soul, therefore the same person?
Contrary to what a religion like the Jehovah’s Witnesses teaches, the Bible speaks of the Holy Spirit being a separate person of the Trinity.
I would encourage you to look up Bible passages like these: Matthew 3:16-17; 12:31-32; 28:19; John 14:16; 15:26; 2 Corinthians 13:14.
The Athanasian Creed states biblical truth when it says: “We worship one God in three persons and three persons in one God, without mixing the persons or dividing the divine being. For each person—the Father, the Son, and the Holy Spirit—is distinct, but the deity of Father, Son, and Holy Spirit is one, equal in glory and coeternal in majesty…So the Father is God, the Son is God, the Holy Spirit is God; yet they are not three Gods, but one God. So the Father is Lord, the Son is Lord, the Holy Spirit is Lord; yet they are not three Lords, but one Lord…The Holy Spirit is neither made nor created nor begotten, but proceeds from the Father and the Son.”
