In comparing how the presence of the Holy Spirit is understood in Reformed and Pentecostal-Charismatic worship many differences come to the fore. In accounts of Reformed worship his presence is less prominent than in Pentecostal-Charismatic accounts and is understood in close relation with a fixed set of means of mediation. In Pentecostal-Charismatic worship this connection is unconsciously connected to different means of mediation: bodily engagement and music. This comparison reveals deeper theological differences between the two traditions concerning the image of God and his Trinitarian nature. From this theological analysis the Reformed tradition can learn from Pentecostal-Charismatic worship by emphasizing more clearly that the Spirit is present in worship, by an improved reflection of the freedom of the Spirit in its order of worship and through a more embodied liturgy.
