This is worth considering, from latest Reformed Worship mag.

"A worship service that portrays the offering, duly collected and dedicated, as a means of supporting the life and mission of the Church is a worship service with a vastly reduced understanding of the Church’s participation in the eternal self-offering of its Lord. Even when the eucharist is not celebrated, the offering should be understood eucharistically in terms of being united by faith with our great High Priest’s eternal sacrifice, that we may plead and receive its benefits and offer ourselves in prayer and praise to the Father."

And earlier...

"The ascended Christ is the one true worshiper in whom, with whom, and through whom, and by the Spirit, the Church’s own meager offerings of praise and thanksgiving are joined, perfected, and offered to the Father."

And earlier...

"This last point is most important for helping us understand the basis for intercessory prayer. It is interesting to note that Diebold Schwarz, one of the forerunners to the Genevan Reformation, located the prayer of intercession within the eucharistic prayers of consecration and thanksgiving, thereby acknowledging that intercessory prayers are inextricably linked to the intercessory work of Christ in his role as High Priest. Calvin maintained this practice.

Of particular significance here is the idea that in prayer the Church does not merely participate in the benefits of Christ’s work—it participates in the work itself."

Interesting.
