Spirit of Christ. Spirit of the Father
The Holy Spirit is NOT Christ or the Father. He is a representative of both but a different PERSON.
The Holy Spirit is the Comforter, in Christ’s name. He personifies Christ, yet is a distinct personality. Ms93.1893.8
When He is described as the Spirit of Christ it means that He is representing Christ. When described as the Spirit pf the Father, then He is representing the Father.
However He is distinct from Christ and The Father meaning that He is another person. The third Person of the Godhead
