United and uniting churches

United and uniting churches are churches that have joined together to form one big church. They might have come from different religious backgrounds, such as Protestant or Catholic, but they have come together to form one big church. It's like when you have a big family reunion, you get a lot of different people coming together and joining up, even though they might be from different backgrounds and have different opinions. The same thing happens when churches come together - they join up and become one big family!
