St. Francis's call is a call to return to the basics of Christianity. It is a call to Christians to reach back to their roots so that their spiritual lives can draw strength from the pure waters of the Gospel instead of being choked by manmade traditions and worldly concerns.St. Teresa of Calcutta saw the rapid changes taking place in the world and among its people. She asked individuals to contemplate the meaning of ideas such as home, love, and family and to be open to new conceptions of these terms in the midst of our changing world. In doing so, St. Teresa introduced a new, modern way of doing missionary work, led an international religious organization, and was beloved by people the world over for the work she did out of love for her family, which would one day grow to include all of humanity.
