A new, innocuously titled book, Mother Teresa: Come Be My Light (Doubleday), consisting primarily of correspondence between Teresa and her confessors and superiors over a period of 66 years, provides the spiritual counterpoint to a life known mostly through its works. The letters, many of them preserved against her wishes (she had requested that they be destroyed but was overruled by her church), reveal that for the last nearly half-century of her life she felt no presence of God whatsoever — or, as the book's compiler and editor, the Rev. Brian Kolodiejchuk, writes, "neither in her heart or in the eucharist."
That absence seems to have started at almost precisely the time she began tending the poor and dying in Calcutta, and — except for a five-week break in 1959 — never abated. Although perpetually cheery in public, the Teresa of the letters lived in a state of deep and abiding spiritual pain. ...
For all that she had expected and even craved to share in Christ's Passion, she had not anticipated that she might recapitulate the particular moment on the Cross when he asks, "My God, My God, why have you forsaken me?" The idea that rather than a nihilistic vacuum, his felt absence might be the ordeal she had prayed for, that her perseverance in its face might echo his faith unto death on the Cross, that it might indeed be a grace, enhancing the efficacy of her calling, made sense of her pain.
