What term describes someone who is deeply devoted to religion?

The term that best describes someone who is deeply devoted to religion is "devout." This word specifically refers to individuals who show sincere and earnest commitment to their religious beliefs and practices. A devout person often participates actively in their faith, upholds its teachings, and demonstrates a strong connection to their spiritual community. This devotion can manifest in various ways, including regular attendance at religious services, prayer, and a lifestyle aligned with their religious values.

In contrast, the other terms provided do not relate to religious devotion. "Discerning" refers to being able to make good judgments or having insight. It does not imply a commitment to religion but rather an ability to distinguish between different options or truths. "Dissent," which refers to the disagreement with a commonly held opinion or established authority, and "dissension," which signifies disagreement that often leads to conflict, do not capture the essence of devotion or commitment to faith. Thus, "devout" is the most accurate term in the context of religious dedication.
