Each church in the united church, pays what is called and assessment to the next up body of the church, the presbytery.  The presbytery pays an assessment to the conference.  And the conference as well, often receives a grant from the national church which comes from the mission and service fund, which is collected - voluntarily - from the people who worship in the congregations.

So our high school celebrated Remembrance Day on Tuesday. I have English class with two twins, who I recently learnt were Jahovan Witnesses (spelt right?) They've never stood up for the national anthem, and I kinda understand that, with the religious ties in the anthem and all, but I was really surprised the on Tuesday. When they asked everyone to stand up for the two minutes of silence, they just kinda sat there staring at eachother, quietly stating the odd comment. I was really offended!
