Born as Agnes Bojaxhiu in Skopje, Ottoman Macedonia, Mother Teresa felt a divine call to serve humanity at just twelve years old. After joining the Loreto Sisters in India and becoming Sister Teresa, her life took a pivotal turn in 1946 when she experienced a 'call within a call,' urging her to leave the convent to devote herself fully to the destitute of Calcutta. In 1948, she founded the Missionaries of Charity, an order focused on caring for the orphans, lepers, the blind, and the dying, establishing hospices and centers that would spread across the globe. Her extraordinary humility and relentless love for the suffering earned her global acclaim, culminating in the Nobel Peace Prize in 1979 and canonization in 2016. This book delves into the compelling narrative of a modern saint, exploring the mysticism in her visions of Christ, the public controversies surrounding her methods, and the striking contrast between her saintly image and the criticisms she faced. It reveals how this West-educated nun transformed her life to serve the poorest of the poor, illuminating the intersection of social issues and faith against the backdrop of mid-20th-century history. Mother Teresa's profound legacy, marked by her unforgettable words and the simplicity of her spirituality, inspires millions. Through personal struggles with spiritual dryness and the embracing of her public persona, her life is a testament to unwavering compassion that continues to resonate today.
