Christian denominations (around 40,000 and counting) and religious clubs that have formed over the years, came into existence, because people stopped walking in the middle of their journey with God.
They get an explosive revelation of a minuscule aspect of God, and declare: "This is it! We've got it all!". And after the the initial euphoria dies down, the newly-discovered revelation is cemented with a long-faced, "Those who differ with us, are heretics!"
This is what I call religion.
Religion is not a group of people, or an organization. It is a sincere, closed, dogmatic and an insecure mindset.
This is also how close-minded traditions are formed.
While it's fashionable to look down on traditions (while presuming "we" are on the cutting edge of God's revelation), we become Traditionalist 2.0, the moment we pitch the tent.
Humility and simple logic acknowledges the obvious - that, the elephant is indeed, much bigger than what our limited senses can comprehend.
