The first view—probably the commonest and most widespread—is that worship is something which we do—mainly in church on Sunday. . . .
The only priesthood is our priesthood, the only offering our offering, the only intercessions our intercessions.
Indeed this view of worship is in practice unitarian, has no doctrine of the Mediator or Sole Priesthood of Christ, is human-centred, with no proper doctrine of the Holy Spirit, is too often non-sacramental, and can engender weariness. We sit in the pew watching the minister ‘doing his thing’, exhorting us ‘to do our thing’, until we go home thinking we have done our duty for another week! . . .
The second view of worship is that worship is rather the gift of participating through the Spirit in the (incarnate) Son’s communion with the Father —of participating, in union with Christ, in what He has done for us once and for all in His self-offering to the Father in His life and death on the Cross, and in what He is continuing to do for us in the presence of the Father, and in His mission from the Father to the world. . . .
The Gospel of grace, that our Father in the gift of His Son and the gift of the Spirit, gives us what He demands—the worship of our hearts and minds—lifting us up out of ourselves to participate in the very life of the Godhead. . . .
Whereas the first view can be divisive, in that every church and denomination “does its own thing” and worships God in its own way, the second is unifying, in that it recognises that there is only one way to come to the Father, namely through Christ in the communion of saints, whatever outward form our worship may take.
