I think it's a very good idea, it means we not only use the money from bitcoin to have fun but rather set aside for donations of places of worship such as churches and other places of worship, in order to materialize the idea we should start it by inviting bitcoin holders to participate in donations for their respective places of worship, without coercion and for those who want it, that's my opinion.
Agree, because its very useful currency that they can use there for their billings, like their electricity in the church and other purpose. Maybe on this way bitcoin may spread of their leaders or religious sectors to their church, and they spread goodnews to other people.
