A lot of people have put some quite personal things on this thread, which I have been following closely, so I feel that I should share my own perspective.
I have never been a worshipper, but an adored family member became swept up in a charismatic church as a result of Christian Union involvement. The first warning bell rang for me when they were encouraged to make a good-sized donation to a church, at a very young age. I won't put identifying detail (it's not my story to tell), but their history of church involvement involves everything that you might expect: tithing income, huge amounts of time spent on church activities and, later, significant family sacrifices for a religious purpose. Their involvement with the church has also formed a huge barrier between us - there are certain things that we just cannot talk about as our values are so different...
Funnily enough, I do actually believe in God: a God who does not require a book, a building, a group of people, a leader or regular donations to be celebrated. However, I also believe in truth, reason and the values of civil society. None of these church organisations lie outside the law or the potential for change, especially when it comes to their influence over young or vulnerable people.
What steps could be taken to make change?
