3.5.1.1 The Holy Spirit in unity with the Father and the Son

The Creed of Nicaea-Constantinople (see 2.2.2) states that the Holy Spirit emanates from the Father and the Son. According to the words of Jesus, the Father and Son are senders of the Holy Spirit in equal measure: "But when the Helper comes, whom I shall send you from the Father, the Spirit of truth who proceeds from the Father, He will testify of Me" (John 15: 26). The Holy Spirit proceeds from the Father (John 14: 26) and is sent by the Son, and therefore also proceeds from the Son (John 16: 7). Thus the Holy Spirit is both the Spirit of the Father and the Spirit of the Son. This is also expressed in Jesus' words: "He [the Holy Spirit] will glorify Me, for He will take of what is mine and declare it to you. All things that the Father has are Mine" (John 16: 14-15).

Thus, an understanding of the Holy Spirit's nature only becomes clear in view of His oneness of substance with the Father and the Son. Like the Father and the Son, the Holy Spirit is "very God of very God". He is not created, but is rather of one substance with the Father and the Son and, like them, He is active eternally.
