If looking at salvation as a human right can be seen as valid, then the question is whether it is useful. What, if anything, can be gained from this perspective. Here are a few VERY TENTATIVE suggestions.
It firmly places salvation within a community. It has been common for Christians, especially Evangelical Protestant Christians to focus on the individualistic aspect of salvation. That is quite valid, but the Bible expresses salvation in both individualistic and communitarian terms. In this sense it is more like the public health perspective. Lostness in an individual is a social ill, a failure for the individual members to flourish to their potentials.
Lostness would be seen as a problem. If condemnation is getting what one deserves, then one might argue that condemnation is not really a problem. If salvation is a human right, then lostness is a problem that must be addressed.
It does condemn community complicity in lostness. The public health perspective, or the disease model, is often seen avoiding judgment. This is especially true in the United States, but also true in places like here in the Philippines. When we label a social ill as a disease, many people decry that saying that pulls it out of ethical scrutiny. There is nothing inherent to that, of course. To call addiction a disease does not remove moral issues or judgment from it. Still, the public health perspective does tend to downplay the ethical. Identifying hunger as a public health problem certainly does get people thinking about what can be done to solve the problem. However, if one says that it is a human right for each person to have enough food daily to live, then there is a more clear condemnation of any society that accepts the condition where some people in the society do not have enough food to eat, while there is overall enough food to go around. Likewise, if salvation is a “public health” problem, then it is a problem that must be rooted out and addressed. On the other hand, if salvation is a basic human right, then the community that makes salvation unavailable, through inaction or through making salvation appear undesirable, is held accountable for this. It other words, embracing an ancient metaphor, if the church holds the “keys to the kingdom,” then if people find the door locked, then the church is culpable.
Seeing salvation as a human rights issue balances the focus between God and Mankind. In the criminal justice perspective, God is the standard, the judge, the mediator, and the provider of salvation. This is not wrong. With the public health perspective, salvation is seen as a more human activity. It is a disease that must be rooted out, from causes, the hindrances, to opportunities, and then to holistic transformation and flourishing. God is there, but the human aspect is given greater attention. This is not inappropriate. However, the human rights perspective draws from both. It takes seriously our humanity and communal responsibility for making salvation available, and living out our salvation. However, salvation as a human right only has real meaning if understood as instituted by God.
So is one perspective right and the others wrong? There is great benefit to intersubjectivity or multi-perspectival understanding. Each overcomes the weakness of the other, giving a fuller understanding of what is real– God’s activity for us.
