I have read 2 biographies of Mother Teresa, but she first came to my attention through Malcolm Muggeridge’s film and attendant book Something Beautiful for God. Of course Muggeridge showed Mother’s work with the dying and the poorest of the poor on the streets of Kolkata, but what moved me the most were the images of the saint’s smile amidst so much squalor and suffering. She was a very bright light shining in exceptionally thick darkness.  
Mother’s life reveals so many aspects and profiles of holiness, but I would like to focus on three of them. First, she shows something remarkable about love, which is not a sentiment but rather willing the good of the other. I think it is fair to say that Mother Teresa went to extremes in demonstrating love in this proper sense. She renounced practically everything that, in the opinion of the world, makes life pleasant—wealth, material goods, power, comforts, luxuries—in order to be of service to those in need. Further, for decades, she personally reached out to the most vulnerable in one of the worst slums in the world and sent her sisters to some of the most disagreeable places on the planet. Most of us, I imagine, manage to love to a degree, but few ever express this theological virtue more dramatically and radically than she did. This is not simply admirable, it constitutes a crucial witness to the nature of love.
Unlike the other virtues, both natural and theological, love has no limit. Justice, limitlessly expressed, excludes all mercy; too much temperance becomes a fussy puritanism; exaggerated courage is rashness; unlimited faith is credulity; infinite hope devolves into presumption. But there can never be too much love; there is never a time when love is inappropriate, for love is what God is, and love constitutes the very life of heaven.  Love remains in all of its infinite      intensity and radicality. Mother Teresa’s way of life, accordingly, is an icon of the love that will obtain in heaven, when we are drawn utterly into the very life of God.
