“As important and revolutionary as these things were, it was Joseph Smith's teachings on marriage that had a more visible and far-reaching effect on William Clayton's life than anything else he learned in Nauvoo. Two doctrines, “eternal marriage" and "plural marriage," went hand-in-hand, and Clayton learned of them during the last two years of his association with the prophet.

Why would the straitlaced, idealistic William Clayton, who was almost overly concerned with what people thought of him, seriously consider the practice of plural marriage when it so clearly violated all his earlier values as well as the morality and sensibilities of the society in which he lived? He had a good marriage with Ruth Moon, which had endured considerable adversity. He was also close to her family. By the time the doctrine of polygamy was presented to him Ruth had borne three children and on February 17, 1843, just two months before his second marriage, she presented him with his first son. It was no lack of love or compatibility that led him to take additional wives. The most compelling factor was his single-minded conviction that whatever Joseph Smith told him to do was right and that he must spare no pains to accomplish it. At the same time, it is clear that his affection for Sarah Crooks of Manchester was still there, and once he was convinced that the principle was true, it was only natural that he should think of her as a possible second wife.”
