And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. (Philippians 2:11)

Philip saith unto him, Lord, show us the Father, and it sufficeth us. Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Show us the Father? Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works. Believe me that I am in the Father, and the Father in me: or else believe me for the very works' sake. (John 14:8-11)

See how the Holy Spirit is regarded on the same level as God:

(Acts 5:3-4)

The Holy Spirit was active in the Creation week:
