No, Mother Teresa is not recognized as a saint by the Catholic church. Although Mother Teresa has not been formally recognized as a saint as of 2014, many Christians from different denominations regard her as a modern-day saint.
Many believe that Mother Teresa, born Agnes Gonxha Bojaxhiu, is bound to one day be recognized as a saint by the Catholic church. She was beatified in 2003, reaching the rank of blessed, but another miracle credited to her intercession must occur before she can reach sainthood. The beatification occurred as part of an ongoing process to declare her a saint after her death. Before her death, she was the recipient of numerous honors and awards for her devotion to caring for the sick and poor.
