1. Privatization
Religion becomes more privatized‘especially without the reinforcement of widely shared cultural practices (such as the rhythm of holy days, festivals, and Sunday observances) and public policy (such as state support for a particular church, anti-blasphemy laws, and religious instruction in schools).
2. Pluralization
Privatization leads to pluralization, especially as new immigrants arrive with varied religious backgrounds. Religious pluralism, of course, is a fact’especially in Europe and in North America. Religious freedom is a right. However, these two facets of pluralism are often confused in people's minds with the idea that all religious paths are equally true.
3. Relativization
This leads typically to the relativization of truth-claims as those practicing a particular religion are reluctant to defend their beliefs as true for everybody and increasingly commend their private commitments merely as personally useful and meaningful.
4. Psychologization
At last, religion is reduced to a form of personal therapy, as objective claims are psychologized into subjective experience. "God" becomes equivalent to a "source of inner empowerment," and the Bible's historical plotline of creation, fall, redemption, and consummation is turned into an individualistic and inner striving, from an autonomous selfhood to dysfunction to recovery and self-enlightenment.
According to this story, we came from nowhere and are going nowhere, but in between we can make something of ourselves. To the extent that we see the basic trajectory of this process in evangelical circles today as well, we should not be surprised to discover in the latest statistics that the sharpest rise among those who do not claim any religious affiliation is among evangelical as well as mainline Protestants. Accommodating ourselves to the culture of modernity, we can no longer use the old growth-versus-decline argument as an anti-mainline polemic.
