As it turns out, there isn't a particular "perfect" way to come up with good fundraisers for a church, as there are many fundraising activities that can be adapted to work well in different situations. The way you have to look at things is by considering the fundraising team you have, which is probably members of the congregation, and the people they'll be selling to. This combination of salespeople and customers will give you a good ideas as to which fundraisers will work best for you.
The size of your fundraising group has a lot to do with which fundraisers for a church you should consider first. If you are quite a small group, you should probably be looking at fundraisers for a church with low or no minimum order requirements, and high profit returns. Many direct sale fundraisers have free shipping, and for fundraising ideas like pizza fundraising cards, you can make profits of up to 90%. These can be fantastic fundraisers for a church if your goals are moderate and your fundraising team not very large. If you do have a larger group, however, you may as well go for something like pretzel fundraisers, which is a top selling item and only really works well as a fundraising idea for a church groups that have a lot of people working together. It all depends on which fundraisers for a church match up well to the group you've got, and the goals you want to meet.
