Public health skills are powerful tools to promote flourishing of communities; they complement medical care of individuals. Christians also want to promote human flourishing, since this demonstrates the goodness of God. What will characterize public health done by Christians?
Some of the ancients were inclined to treat disease and plagues in terms of supernatural forces and magic, shamanism and religious practices. The Hebrews stressed regulation of personal and community hygiene, isolation of lepers and other ‘unclean conditions,’ and family and personal sexual purity; God gave to Moses commands related to a weekly day of rest, limits on slavery and oppression, sanitation and food regulations. The children of Israel gave to the world the teaching concerning human dignity since all are made in the image of God.
Modern public health is a noble sphere of human endeavor, whether done by Christians, Muslims or Secular modernists. Good public health practice should be characterized not only by good science but love for humankind. Christians are especially motivated by the value of human beings, as well as God’s command to love the Lord our God with all our heart, and love our neighbor as ourselves. We glorify God by seeking His best for our fellow human beings.
At the same time, modern public health – Jenner and vaccination, Snow on cholera, germ theory, bacteriologic revolution, hospital reform, immunology, the development of epidemiology – has grown up as part of the modern scientific revolution and out of Enlightenment thinking. It is often characterized by a ‘split’ of sacred and secular, and a peculiar perspective that things ‘scientific’ define reality whereas things of God are confined to personal and private belief. I believe this is an inadequate foundation for public health as it tends to relegate ethical and moral matters to a private and subjective world.
As Christians we have much we can learn from our public health teachers, and much to give in order to alleviate the suffering of this world. But ultimately our motivation for doing public health is to demonstrate the character of Jesus Christ to the world; we cannot bring utopia to this world but we can point to a Savior who cares about men and women – body and spirit. He is the Savior who not only frees us from our sinful selves but also frees us for His purposes in a world which He has made and is in the process of re-creating.
As a Christian epidemiologist, I will use the techniques of case control studies, disease surveillance and risk identification just the same as anyone else. The tools are the same, whatever our faith orientation. Our desired outcome – disease prevention and health promotion – will be the same; public health professionals seek the best for others. Christian public health is not just public health done by Christians; it becomes activities, programs, policy and advocacy informed by God’s Word – which commands us to ‘love justice, seek mercy, and walk humbly with.. God.” (Micah 6:8)
A Christian perspective on public health and human flourishing will be informed not only by material success, but also by an understanding of the darker forces we face, including suffering and death. It will seek to address these matters with courage and meaning. A Christian perspective on public health can deal with life well because of the hope God offers in His promises in both life and death. The cross of Jesus Christ has won the victory of sin, darkness and rebellion in order to usher in life here and eternally.
Ultimately health is not an achievement of man but a blessing of God. And He is working in the world to bless the world through His Son Jesus Christ, who gave His own life for the ultimate in public health – salvation from sin, rescue from darkness and oppression, and the freedom of a life of love and grace.
