If preaching the gospel is a man's duty, it is equally a woman's duty

According to the principle which I have laid down, that man and woman were created equal, and endowed by their beneficent Creator with the same intellectual powers and the same moral responsibilities, and that consequently whatever is morally right for a man to do, is morally right for a woman to do, it follows as a necessary corollary, that if it is the duty of man to preach the unsearchable riches of Christ, it is the duty also of woman.
