Missiologists have in recent years begun to think seriously about inculturation, and historians have begun to learn from them. When the Christian message is inserted into a cultural framework, if the messengers are insensitive to the local culture the result can be cultural imperialism. On the other hand, if they grant too much hegemony to the local culture, the result at best is 'syncretism' and at worst 'Christo-paganism.' Things are most wholesome when sensitive interchange takes place leading to 'a truly critical symbiosis.' But for this to happen, there must be a second stage - a time of 'pastoral follow-up work,' of catechizing and life formation enabling the new faith to express its genius in the institutions and reflexes of its new host culture.
