Dave: It's curious how of all religions ever created it was Christianity that conquered the world
Lukas: It's simple. Nations with Christianity as main religion happened to be most aggressive and most developed nations.
Lukas: And they were using their power to convert weaker nations.
Lukas: In the end it's the matter of power and influence.
Dave: But why did Christianity happen to be present in strongest civilizations?
Lukas: Religion was once closely connected to ruling over a country.
Lukas: Religious leaders had much more to say than court members.
Lukas: So it was obvious that expansion towards foreign lands mean that culture of conquered state should be banished and replaced by culture of aggressor.
Dave: If it was not for religion, we would have space travel now...
Lukas: Maybe...
Lukas: Maybe not. I don't know
Dave wonders why Christianity appeared to be the most powerful religion in the world. Lukas tries to answer Dave's questions by explaining the historical background of Christian Expansion.
