What lifestyle is associated with members of the laity?

Members of the laity are individuals who are not part of the clergy or religious order, which means they do not hold religious authority in a formal sense. The lifestyle associated with them is referred to as secular, as it pertains to the everyday life and activities of individuals who may or may not be involved in religious practices but do not have a dedicated role within the religious institution itself. Therefore, the correct answer highlights the distinction of the laity's life as being oriented towards the secular world, reflecting their participation in various social, political, and cultural aspects without the obligations that come with religious authority or professional clergy roles.

Other options, such as professional, religious, and academic lifestyles, do not accurately capture the essence of the laity's lifestyle, as these either imply a focus on a specific career, dedication to religious life, or scholarly engagement, respectively, which are not the hallmarks of laity.
