In this dialogue, a Catholic character challenges a Quaker's belief about the future stance of religious leaders on issues like slavery, which has been accepted in biblical times. The Catholic expresses skepticism about whether these leaders will ever declare something that was traditionally condoned as wrong, highlighting a tension between historical religious teachings and contemporary ethics.

The Quaker, in turn, reveals a personal mission to persuade their own religious community to denounce slavery, indicating that there is currently no consensus within that faith. This exchange underscores the complexities of morality within religious frameworks, illustrating the struggle between established beliefs and evolving moral understandings.
