So why not just destroy the letters, or forge replacements?
While googling around I found these...
Lord, my God, who am I that you should forsake me? The child of your love – and now become as the most hated one – the one you have thrown away as unwanted – unloved. I call, I cling, I want, and there is no One to answer – no One on Whom I can cling – no, No One. Alone. The darkness is so dark – and I am alone. - Unwanted, forsaken. - The loneliness of the heart that wants love is unbearable.-Where is my faith?-Even deep down, right in, there is nothing but emptiness and darkness.-My God-how painful is this unknown pain. It pains without ceasing...What are you doing my God to one so small? When You asked to imprint Your Passion on my heart – is this the answer?
If this brings You glory, if You get a drop of joy from this – if souls are brought to You – if my suffering satiates Your Thirst – here I am, Lord, with joy I accept all to the end of life - & I will smile at Your Hidden Face – always.
My own Jesus, do with me as you wish - as long as you wish. I am Your own.”
IF those are in context it puts a dramatically different spin on the whole thing. Many of us could write that last bit and mean it... as long as things didn't get too rough. To write it under her circumstances indicates a quality of Faith that makes what the rest of call faith look like a pale imitation.
Probably because there have been a lot of those letters floating around for 50 years to a lot of people.
It is also interesting in context that she chose the name Teresa after Thérèse de Lisieux, the Little Flower, patron saint of missionaries, Doctor of the Church…
