What is the main teaching of the Sermon on the Mount in Christianity?

The Sermon on the Mount is a foundational teaching in Christianity that emphasizes the principles of love, humility, and compassion. This teaching, found in the Gospel of Matthew chapters 5-7, includes the Beatitudes, which highlight values such as mercy, purity of heart, and a thirst for righteousness. It calls on followers to treat others with kindness and love, even extending these virtues to one's enemies. The emphasis on inner morality over mere legalistic observance of laws exemplifies a deep commitment to interpersonal relationships guided by love.

This focus on love and compassion extends to various aspects of life, including how one should live, interact with others, and engage in prayer and charitable acts. The Sermon sets a standard for ethical conduct that goes beyond ritualistic practices or external observances, aiming instead to foster a community grounded in mutual respect and care.
