The idea of an after-life or a reincarnation is mostly irrelevant to people who live in a secular society where they have access to a huge body of knowledge in libraries and on the Internet.
This is mainly because digitization, high speed data processing, and the scientific method of research has produced rational answers to many questions that were previously in the domain of religious opinion.
Our new level of rational knowledge makes traditional religious opinions appear superseded and irrelevant.
If religious opinion is mostly outdated then it's reasonable to think that people are unlikely to study much about religion beyond its social-economic affect and the psychological group-think affect in believing groups.
In predominantly secular environments where people are strongly influenced by the cult-gods of fashion, beauty, entertainment, or career development young people may have very little knowledge of the faith of thousands of early Christians who were tortured to death by the Romans.
Unlike many people today who treat physical death as an existence-terminating experience to be avoided for as long as possible the early Christians believed death was the portal that took them to an extended resurrection life.
Some Church opinions today appear about as rational as a belief in fairies, but there are many early Christian Church beliefs that are as relevant now as they were before Christianity became a State religion under the Roman Emperor Constantine.
To appreciate those beliefs we need to know about the early Christian church formation that happened when Roman authority was under stress throughout the Empire. In that environment Christian beliefs developed and spread widely, even to Rome, where the opinions of St. Paul still have an enduring influence.
The Romans were certainly brutal rulers but brutality is just as common now as the world experiences growing political and environmental turmoil. There's no quick solution to the many problems we hear about daily on TV and in the news, and there are no suggested solutions on this site either. There are, however, short thought-provoking articles written from a personal perspective.
If you have traveled abroad you may have noticed how strong local religious beliefs can be, and you may also have noticed that there appear to be many people who need to dominate other people and dictate commands to them, often with the threat of physical or economic sanctions if people decide to resist.
Those two observations are sufficient to prompt a series of thoughts that are superficially developed in the Culture Clash article which promotes the belief that we should care for others and work towards the removal of dictatorial politics from the world scene.
