“Although some religious conservatives warn that the retreat from faith will lead to a collapse of social cohesion and public morality, the evidence doesn’t support this claim. As unexpected as it may seem, countries that are less religious actually tend to be less corrupt and have lower murder rates than the more religious ones.” (Ronald F. Inglehart, “Giving Up on God; The Global Decline of Religion,” Foreign Affairs, September/October 2020)
Inglehart cites several factors in the noticeable decline of religion in the United States and other developed societies.
One is the greater security people may feel when their material needs are more easily met. They don’t feel a need to depend on a divine being to protect them from material want.
Also, as gender and sexual norms are relaxed, religion becomes less important in enforcing those norms.
However, Christianity began in the more secular society of the Roman empire. The Roman empire was fairly moderate in terms of religious freedom, so long as no religion advocated the overthrow of Rome.
Jesus taught his disciples not to worry about material things but to be more concerned about seeking God’s kingdom and righteousness. He did not, however, seem to forbid wealth in itself and even enjoyed fellowship with some who were well-off.
Though the early Christian communities taught care of the poor, some of the early Christians were well-off and shared their wealth. They also included the learned, like the apostle Paul.
The attraction to the religion of Christ has, throughout the centuries, included those who care for the poor, such as many religious communities in the Middle Ages. Material support for these communities often came from the well-off.
Christianity often spreads through a minority, but a minority that encourages practices that benefit society as a whole. In America, some Christians advocated for the abolition of slavery. Others advocated for universal access to education. Still others began missionary societies that cared for the poor and the sick even as they evangelized.
A belief in the worth of all people also contributed to the growth of more democratic forms of government.
Christianity is not necessarily limited in ultimate results by being a minority.
Religion, including Christianity, can be corrupted. Yet, throughout the centuries, each failure within the Christian community has birthed a minority who not only overcame the failures but found new ways to grow.
