Actually, Christianity's most enduring and impressive foe is western imperialism. Western imperialism, either by brute force or through a subtle co-opting of the Church, has often come close to defeating Christianity. However, there has always been a group of Christians(sometimes small and sometimes opposed by the hierarchy of their church) who have continued to fight western imperialism. They have been do so since literaly day one and may they continue to do so.
