Ray aided the cause of liberty by lending practical aid which men in high places often had neither the time nor the patience to give, using his home as a mecca for the meetings of such men as Lewis Tappan, Simeon S. Josselyn, Gerrit Smith, the land philanthropist, and James Sturge, the celebrated English philanthropist, interested in the abolition of slavery. In cooperation with wealthy abolitionists he assisted many a slave to the light of freedom, especially through the aid of Henry Ward Beecher of the Plymouth Church in Brooklyn. Ray found himself cooperating also with the group of radical free people of color meeting in Philadelphia and in other cities of the North from 1830 until the Civil War. When one reads of his participation in this work with James Forten, a business man, and Charles B. Purvis, another layman, he is inclined to forget that Charles B. Ray was a minister, as his name appears in the records of practically all of these conventions of the free people of color and his work stands out as an important factor contributing to the success with which these aggressive Negroes kept their case before the world and gradually hastened the dawn of their freedom. In all of his various employments, however, Ray did not lose interest in and did not necessarily neglect his mission to promote the moral uplift of his fellows. A contemporary, William Wells Brown, paying him a tribute as a terse, vigorous writer and an able and eloquent speaker, well informed upon all subjects of the day, says also that he was "blameless in his family relations, guided by the highest moral rectitude, a true friend of everything that tends to better the moral, social, religious and political condition of man."
