Saint Theresa Yi Mae-im

Saint Teresa Yi Mae-im (1788–July 20, 1839) was a Korean martyr and a saint of the Catholic Church. Teresa Yi Mae-im was the aunt of fellow Catholic martyrs Barbara Yi Chŏng-hŭi and Magdalena Yi Yŏng-hŭi. During the persecutions, Teresa Yi Mae-im and three other pious women—Lucia Kim Nusia, Marta Kim Sŏng-im, and Magdalena Yi Yŏng-hŭi—surrendered themselves to the police. She was beheaded on July 20, 1839, at the execution site outside the Small West Gate in Seoul, alongside seven other Catholics: Rosa Kim No-sa, Marta Kim Sŏng-im, Anna Kim Chang-gŭm, John Baptist Yi Kwang-nyŏl, Magdalena Yi Yŏng-hŭi, Lucia Kim Nusia, and Maria Wŏn Kwi-im. Her feast day is September 20, as part of the group of the 103 Korean Martyrs. She was beatified on July 5, 1925, by Pope Pius XI and canonized on May 6, 1984, by Pope John Paul II as one of the 103 Korean Martyrs.
