Final answer:
John Wesley was nearly engaged to Grace Murray, who does not match any of the provided options, before marrying Mary Vazeille. The Wesleys were inspired to their religious conversion by Martin Luther, differentiating from Whitefield, who was influenced by John Calvin.
Step-by-step explanation:
John Wesley, the founder of Methodism, was engaged to a woman named Grace Murray before marrying Mary Vazeille, who would become his eventual wife. Although there might be some confusion due to several Marys appearing in different historical contexts, such as Mary Bennett who was a notable person from the early colonial period of America, it is important to clarify that historically, John Wesley nearly married Grace Murray rather than someone directly named Mary, Elizabeth, Sarah, or Emily. This question seems to be based on a historical figure and their personal life, thus categorizing it under History.
Furthermore, the Wesleys began as Anglicans and were inspired to conversion by the writings of Martin Luther, which contrasts with another prominent figure of the time, Whitefield, whose conversion was greatly influenced by John Calvin. These historical details provide context to the Methodist movement and its founders.
