Religious fanaticism throughout history has caused many evils, including murder and genocide. Secular society is right in fighting against it. Much of the prejudice against religion held by atheists and agnostics is unfortunately justified.
So I’ll leave you with a few tips.
We should accept that every religion has some good and truth to it. We should see other religions and versions of Christianity for their good rather than their bad qualities. We should refrain from making personal accusations or threats. Don’t denigrate such and such a church or religion as false or bogus in relation to your own which is the “true church”. Learn to be kind and patient.
We should learn about other versions of Christianity (denominations, different theological “systems”, etc.) and about other religions. How many of us have read the Koran, even in an English translation? I haven’t, but I have taken the trouble to read some basic introductions to Islam. I know very little about Hinduism or Buddhism, but I know I am missing something unless I take the trouble to learn something.
How open are we to our ordinary life at work and at home? Are we forcing our beliefs on everyone else and judging? Or are we kind and teaching by meekness and example? Are we making friends outside our churches and discussing courteously with people who believe differently or not at all?
Are we prepared to learn tolerance, which does not mean that we do not believe in truth or the validity of what we might consider as wrong? Kindness is much more convincing than brutality either in deed, speech or writing.
We know that fanatics and zealots form a tiny minority in their communities, but like in society at large, they are the bullies, the sociopaths and narcissists that dominate and make life miserable to those who they would like to be lower in the pecking order. They ruin everything for everyone else. The evil is potentially within any of us.
Please comment wisely.
