Credo 36 – With the Father and the Son He is worshipped and glorified…
The Spirit dwells in the Church and in the hearts of the faithful, as in a temple. ‘With sighs too deep for words’, the Holy Spirit prays on their behalf, and bears witness to their adoptive sonship. By the power of the Gospel he makes the Church keep the freshness of youth. Eternally, he renews her and leads her to perfect union with her Spouse. The Spirit and the Bride both say to Jesus the Lord, ‘Come’. (Lumen Gentium 4).
The Spirit is due equal worship with the Father and the Son because of His equality with them as the third person of the Triune God. He is the Advocate which the Father has bestowed on the Church through Christ to lead her and guide her towards the glory of eternal life.
