To understand why Mormons avoid coffee and tea, one must look to the foundational health code known as the Word of Wisdom. This revelation, received by Joseph Smith in 1833, serves as a dietary guideline for members of The Church of Jesus Christ of Latter-day Saints. While often simplified as a ban on coffee and tea, the directive specifically prohibits "hot drinks," which church leaders have interpreted to include any beverage containing caffeine that is not a cola drink.
The Scriptural Basis: The Word of Wisdom
The primary source for this practice is found in the Doctrine and Covenants, section 89. In this text, the Lord states, "Hot drinks are not for the body, neither for the belly." Historically, the early Latter-day Saints interpreted this phrase to refer specifically to coffee and tea, distinguishing them from other stimulants like those found in chocolate or soft drinks. This interpretation has been consistently upheld by church leadership, framing the avoidance not as a preference, but as a commandment tied to spiritual and physical health.
Defining "Hot Drinks"
The term "hot drinks" has remained largely consistent in its application since the 19th century. Church leaders have clarified that this refers to beverages made from tea leaves or coffee beans. This includes black, green, and herbal teas, as well as espresso, lattes, and iced variants. The focus is on the origin of the drink rather than its temperature at the moment of consumption, meaning that while a cold coffee drink might not be hot, it is still prohibited due to its caffeine content derived from the coffee bean.

Health and Wellness Rationales
While the scripture presents the Word of Wisdom as a commandment, members often point to the promised benefits of health and wisdom as validation. Mormons believe that adhering to the guidelines, including avoiding coffee and tea, results in "good health and peace of mind." The avoidance of these specific drinks is seen as a way to maintain optimal physical well-being, avoiding the potential negative side effects of high caffeine intake such as anxiety, sleep disruption, and digestive issues.
A Distinction from Other Caffeinated Beverages
It is important to note that the prohibition is specific to coffee and tea. Many Mormons consume soft drinks like Coca-Cola or Pepsi, which contain caffeine but are not classified as "hot drinks." This distinction highlights that the focus is on the historical "hot drinks" mentioned in the revelation. Consequently, energy drinks, though high in caffeine, exist in a different category of interpretation, with individual members varying in their personal choices regarding their consumption.
Spiritual Discipline and Obedience
Beyond the physical health aspects, the avoidance of coffee and tea holds significant spiritual weight for Latter-day Saints. Adhering to this guidance is viewed as an act of obedience to God, which strengthens faith and discipline. This practice serves as a visible identifier of the faith, setting apart the daily routines of believers. It is a tangible way of living the covenant they have made, demonstrating a commitment to living a life separated from worldly stimulants that might cloud mental clarity or spiritual focus.

Social and Cultural Identity
The prohibition also plays a role in shaping the social environment within the Mormon community. By avoiding coffee and tea, members create a shared cultural practice that reinforces group identity. This extends to social gatherings, where offering water, juice, or herbal alternatives ensures that all members can participate comfortably. It removes the pressure to consume these drinks in professional or social settings, fostering an environment where the community can connect without reliance on substances that are explicitly restricted.
Modern Interpretations and Flexibility
It is worth noting that while the core principle remains, there is a nuanced understanding of health within the church. Some members and leaders have acknowledged that the emphasis is on temperance and health consciousness rather than a rigid legalism. The overarching goal is to maintain a healthy body, which is considered a temple of the spirit. As long as individuals adhere to the specific mandate regarding "hot drinks," the church encourages a balanced and thoughtful approach to overall wellness, leaving room for personal agency in other dietary choices.
