I don't understand the obsession Cathalocism have with converting Asian/African cultures to Christianity and then make them donation slaves of Roman Catholic Church. Can't they just mind their own business rather than funding ridiculous missions.
If you strongly and sincerely believe that you have some key knowledge on skin disease, say you were the first person to discover a working sunblock to prevent cancer, would you not go and try to get people to use it? If you realised the value of seatbelts before anyone else, would you not start a world-wide campaign to improve road safety?
Christians are like this. They don't view missionary work as "trying to embiggen the Church", they view it as going out to save people lives, in this realm and the next, since they sincerely believe the way to do this is with a relationship with God.

The other people might not believe you, and you might end up being wrong about some or all aspects of what you thought you had discovered, but it makes sense that you would feel an urgency in letting people know about it.
