The government would have to clearly define what charitable services count, if you remove religious services from there then a lot of churches would become group therapy and community support centers legally to maintain the definition of a charitable non taxed service.

For the record. Most churches do actually offer this.  Almost all my local churches have addiction groups or grief l, or some form of the other.

I even had a church with a group for self love and overcoming personal animosity.
