Rev. T. B. Ray was Educational Secretary of the Foreign Mission Board of the Southern Baptist Convention. Ray said in the introduction, oI have endeavored to draw a picture of the religious situation in Brazil by reciting facts. I have described some of the work of others done in former years and I have recorded some wonderful manifestations of the triumphant power of the gospel, which I was privileged to see with my own eyes. These pages record testimony which thing, I take it, most people desire concerning the missionary enterprise. More arguments might have been stated and more conclusions might have been expressed, but I have left the reader to make his own deductions from the facts I have tried faithfully to record.o Although Ray traveled throughout South America he confined this text to the work in Brazil. He also spoke only of the mission work done by his denomination."
