Tim Challies posted a brief for medical missions that could help anyone understand why a health gospel is not far removed from a wealth version:
2. You are able to proclaim the gospel at a time in life when your listeners are keenly aware that there are serious problems they cannot remedy in their own strength, and there are worrisome risks they must accept. They know they need God’s help, and they want it. . . .
4. Medical evangelism affords the opportunity to tell people about Christ in the context of helping them with no expectation of personal gain. It confirms that their well-being is your motivation in telling them the gospel.
5. Medical work gives credibility to the evangelist. It shows that he not only wants to help his listeners, but that he can help them. If the physical problem can be remedied, then what the physician has to say about the spiritual problem should be worth listening to as well.
On the flip side, someone might be prone to exhibit faith in order to win the attention of the physician. And sometimes missionaries may want to be thought of as compassionate or humanitarian. Whatever happened to mixed motives?
1. Patients strive diligently to come to you. You do not have to go to them, apologizing for invading their privacy or encroaching on their time.
3. You can evangelize a large geographical area–while traveling only a few miles from home. At Marrere, people came from all over the province and from an additional four states as well. Those five provinces represented half the nation.
Congregations and church buildings accomplish the same purpose, even if indigenous peoples who come to church may be interested in gaining the attention of the Western Christians and the benefits that follow.
6. Mission hospitals provide conspicuous testimonies before entire communities of the transforming work Christ accomplishes in Christians. In primitive cultures, the kind of medical care Christians provide stands in marked contrast to the carelessness and lack of compassion that often characterizes other care-givers.
Or, medical missions show the advances that come from studying bodies as natural phenomena. You don’t need a witch doctor to get well. You don’t need a Christian physician either. What you need is a good medical practitioner.
Why spiritualize medicine? And why, in the process, make the means of grace, word and sacrament, common or even inferior?
Meredith Kline’s logic in his minority report is still worth pondering for the ecclesiology on which it is based. Here is an excerpt:
It is now further to be observed that ithe church finds itself in conflict with the most important principles of biblical ecclesiology as soon as it adopts the traditional approach to medical missions, the approach recommended in the committee’s report. It would seem evident that a physician commissioned by the church to devote his full time to performing in the name of the church what is alleged to be an ecclesiastical function is thereby appointed as some sort of officer of the church. Which office he is supposed to occupy is somewhat obscure-the convenient title of “missionary” is bestowed on him and that covers a multitude of problems. Yet, his work does not coincide with that of any of the church officers as described in’the standards of government of the Orthodox Presbyterian Church. The committee’s report presents his ministry as one of mercy and presumably then he would be, in terms of the committee’s position, a specialized variety of deacon. . . . However, since there is no biblical evidence of deacons or any others practicing ordinaay medicine as an official ecclesiastical function, what the modern church has actually done is to invent the new office of the ecclesiastical medic.
But leaving aside the question of the medical missionary’s official status, there remains the fact that the function of medicine is, according to the committee’s insistence, a properly ecclesiastical function. Therein the committee would find the justification for its policy of medical missions. But if, operating on such assumptions, the church proceeds to commission physicians to practice medicine as an ecclesiastical function, the question at once arises: By what standards is this work to be performed and governed? The church may not abandon responsibility for the nature of the performance of any ecclesiastical function carried out in the church’s name. . . .
Unless, then, the church has lost the third mark of a true churdh and is prepared to disclaim responsibility for exercising disciplinary supervision over its medical work, it will be obliged to adopt a set of standards by which to judge of the medical qualifications of those whom it would appoint and by which afterwards to govern their labors. Such a code of medical practice is, however, not provided in the Word of God.
Presumably, the church will desire to practice medicine according to the present state of the art (that, indeed, becomes the fourth mark of the true church). It will then probably be the latest medical journals that are elevated to the position of standards of the church alongside the Bible. In any case, the Scriptures will no longer be the sole authority and rule in the government of the church. And, of course, there are not available to the church from any source standards of absolute authority and validity for the practice of medicine like the divine norms available to the church in the canon of Scripture for regulating the functions that are indispensably the church’s proper ministry. Thus, when the church usurps to itself from the sphere of human culture the function of medicine, it involves itself in the relativism, the uncertainties, and the fallacies of expert human opinion and repudiates the character of absolute divine authority that is the glory of its true ministry.
Nor is that the end of the dilemma for the church entangled in the medical profession. Such a church must also be ready to submit to the interference of the state in its own proper ecclesiastical functioning in a way clearly prejudicial to the prerogatives of Christ as Head of the church. For the missionary doctor has no license to operate in independence of the civil regulations governing the practice of medicine nor does he have diplomatic immunity from the sanctions of the civil court by which those regulations are enforced. Consequently, the church that commissions him must acknowledge the right of the state to interfere in its government and ministry so far as to determine who is and who, is not qualified to be appointed by the church to one of its own offices or ministries; to establish the particular procedures that the medical appointee must follow in fulfillment of his ecclesiastical ministry; and, in case of malpractice, to inflict temporal penalties on him for his official ecclesiastical shortcomings and virtually to compel his suspension or deposition.
Surely the church that submits to such state interference has thereby removed itself from under the exclusive lordship of Christ as King (in a special sense) of the church. And the church that insists that the practice of medicine is one of its proper divinely assigned functions has no choice but to submit to that kind of state control and in so doing to become guilty of giving unto Caesar that which belongs unto God.

Another reason New Calvinists need a doctrine of the church (but won’t find one at The Gospel Coalition).
