William Wells Brown to Editor, London Morning Advertiser 15 May 1852
Black lecturers educated British audiences about the mechanics of institutional racism in the United States and its impact on northern free blacks. A key component was their indictment of the moderate stance of American churches on the issue of slavery. Even more than Frederick Douglass, who earlier criticized the policies of the Scottish Free Church and the Evangelical Alliance, Brown demonstrated the implications of the American church's failure to indict the practice of slaveholding. Brown's 15 May 1852 letter to the London Morning Advertiser criticized the American Sunday School Union's unwillingness to offend southern slaveholders.

If American pro-slavery divines and others are allowed to come with impunity before a British assembly and speak with approbation, it enables them to spread with much greater facility their opinions in favour of slavery when they are in private circles. Although Dr. Dyer and myself come from the same country, I am not acquainted with either him or his views on the subject of slavery.

In the year 1832, the American Sunday School Union3 published a series of small books, containing an account of some of the most interesting persons and principle events mentioned in the Old Testament. These books were written in a style adapted to the comprehension of children, and well calculated to impress the young mind with a knowledge of the history of the Israelites, from Abraham to the birth of the Saviour.
