Roman Catholic Religion in Comparison to Mennonites?

I need to compare the Roman Catholic religion: like their faith their beliefs, rites, traditions and such to Mennonite Religion as well with their beliefs, rites, traditions. I see to have some information but I can't see to fine things like Purgatory, To whom they pray, And what they stand for. Yes this is for a project and I also need pictures that are interesting, candid preferred but pictures that represent both religions. If you can help it would be very much appreciated. Thank you
