From the review of Protestants Abroad: How Missionaries Tried to Change the World but Changed America, here:
As Hollinger notes, by the end of World War II, commentators such as Congregationalist leader Buell Gallagher were observing that the “gospel of inclusive brotherhood” that missionaries preached abroad had begun to return home like a boomerang to “smite the imperialism of white nations, as well as to confound the churches.” Many missionaries and their families who had been assigned a key role in converting the benighted darker races to Western ways had instead gained abroad an appreciation for cultural diversity and had come back to the United States to challenge “cultural imperialism and arrogant paternalism” and play a leading role in contesting white Protestant hegemony. Hollinger charts the intriguing flight of this boomerang. ... As he sees it, their greatest importance in the 20th century is to be found in the effects of a contradictory, potentially self-annulling belief system.
These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: But go rather to the lost sheep of the house of Israel. And as ye go, preach, saying, The kingdom of heaven is at hand. -- Matthew 10:5ff.
Woe unto you, scribes and Pharisees, hypocrites! for ye compass sea and land to make one proselyte, and when he is made, ye make him twofold more the child of hell than yourselves. -- Matthew 23:15
