There are atheist “churches”, too.
The North Texas Church of Freethought has been running for a decade or more.
The “Sunday Assembly” is a modern and more popular incarnation, though it has already schismed with “The Godless Revival”. No joke, it was in Huffington Post in 2014.
So even secular atheist churches have the same denomination splits protestants do, while mocking the strict doctrinal standards - and enjoying the strong social network religion typically provides.
“Though our outer self is wasting away, our inner self is being renewed day by day.”
-II Corinthians 4:16
The idolatry of self worship reaches its zenith in the extremes that some will go to preserve life and limb. I daresay that NO ONE reading my comments will be physically alive in 100 years, no matter how many organic fruit smoothies they drink, or how many crunches are performed. That’s why it is imperative to know where your eternal soul stands. The health of our spirits is what should consume us, and we should be filled with a zeal to seek after the Father’s glory.
