The Church is more than a "mere" instrument.

I read the following quote by Pastor Herschel Martindale in the Great Commission Leadership Institute materials.

"And he put all things under his feet and gave him as head over all things to the church, which is his body, the fullness of him who fills all things" (Ephesians 1:22-23, ESV). The Church is the body (instrument) of Jesus. Local churches are merely a representation of this universal body or Church. A body is merely an instrument or means by which the purpose of the head is accomplished."

Actually, the article on the whole is good. However, I disagree with the phrase "merely an instrument." I think what Pastor Martincale is saying is the Church is only a means or tool to accomplish the Great Commission and nothing more. It is hard to believe Pastor Martindale used Ephesians 1:22-23 as a defense for his assertion. Ephesians 1:22-23 is one of the passages in the New Testament which magnifies most what Christ has done for the Church and how Christ plans to use the Church not only here on earth but also in the whole of creation. Paul argues in Ephesians that the Church is not only the means, but it is also one of the main goals of His redemptive work. Here is Peter T. O'Brien commentary on Ephesians 1:22-23.

This still leaves the difficulty of how to interpret 'head' in relation to the body. Perhaps if the Old "Testament notions of 'head' are combined with Greek medical ideas regarding the function of the head in relation to the body and its members, then the head is to be understood as 'inspiring, ruling, guiding, combining, sustaining power, the mainspring of its activity, the centre of its unit, and the seat of its life'. Instead of separating Christ from his body, the head is shown to be 'the cohesive and enabling factor for the body'. Accordingly, "Ephesians (and Colossians) highlights the personal presence of a powerful one who strengthens the individual through the concept of Christ as "head"". This interpretation provides the best explanation for Ephesians 4:16 and Colossians 2:19) ('from it [the head] the whole body grows') and it consistent with the thought of the head 'nourishing' the body. (The Letter to the Ephesians, p. 148)

Again O'Brein on Ephesians 1:23,

The conclusions of our exegesis of v. 23, albeit tentative, may be rendered as follows: '[the church, which is Christ's body], the fulness of him [i.e., Christ] who fills all things in every way'. God has given Christ as head over all things for the church. His supremacy over the cosmos is seen to be for the benefit of his people. (ibid, pp. 151-152)

John Piper in a sermon on Ephesians 1 puts it this way:

"Christ fills the universe with his glory by showing the universe his body--how he chose her, how he destined her, how he came for her and taught her and suffered for her and died for her and rose for her and reigns for her, how he called her and justified her and cleansed her and kept her and will raise her and glorify her and satisfy her forever and ever with himself."

The Church glorifies Christ not through what the Church can do for Christ in fulfilling the Great Commission, but by what God does for the Church through Christ's work and the Holy Spirit's ministry. This interpretation does not alter the fact that we are God's instrument in progressing the Gospel, but the Church is so much more. Paul is using "the body" as analogy to communicate a specific message. Paul did not mean for the analogy to say the Church is "merely" an instrument. Another analogy that scripture uses is the Church is the "Bride of Christ." See the following passages:

For I feel a divine jealousy for you, since I betrothed you to one husband, to present you as a pure virgin to Christ. (2 Corinthians 11:2 ESV)

Husbands, love your wives, as Christ loved the church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish. (Ephesians 5:25-27 ESV)

Let us rejoice and exult and give him the glory, for the marriage of the Lamb has come, and his Bride has made herself ready; it was granted her to clothe herself with fine linen, bright and pure”— for the fine linen is the righteous deeds of the saints. And the angel said to me, “Write this: Blessed are those who are invited to the marriage supper of the Lamb.” And he said to me, “These are the true words of God.(Revelation 19:7-9 ESV)

What difference does it make to assert that the Church is merely an instrument? First, it is just a bad interpretation of Ephesians 1. We lose sight of the glory what Christ has done, is doing, and will do for the Church by calling the Church just an instrument. Second, it is bad ecclesiology. If leaders of a local church view their church as just a mere instrument, wouldn't this eventually cause leaders to view the members of their congregation as mere instruments instead of being fellow heirs of the promises? Heirs who need to be loved, nurtured and trained up to be godly men and women in the house of God.
