- Check out these last verses of the Gospel of St. Matthew:
Douay-Rheims Bible (Matthew 28)
 And the eleven disciples went into Galilee, unto the mountain where Jesus had appointed them.  And seeing him they adored: but some doubted.  And Jesus coming, spoke to them, saying: All power is given to me in heaven and in earth.  Going therefore, teach ye all nations; baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.  Teaching them to observe all things whatsoever I have commanded you: and behold I am with you all days, even to the consummation of the world.
Did you get teach ye all nations?
This means, not just individual persons, but institutions - armies, heads of state, cultural personnel and so on - of all nations.
Obeying this command successfully tends to give the one doing so temporal power.
