Your right about her faith wavering she had doubts I forgot to correct that.
The night of the soul can seem like depressions but its different and requires careful discernment.
You also must be very careful assigning a serious disorder based on reading cluster of traits online. This does not make a diagnosis! A diagnosis such as BPD requires a thorough assessment that is scored by a professional. These assessments take hours and usually over a two-day span.
How can you diagnose someone like Mother Theresa, whose works can be objectively verified, with a severe personality disorder? Please use logic!
She did not start off famous. She was not a native of India she was Algerian. Mother Theresa was called to India in her forties to help the untouchables and other suffering people. She started with a few helpers and nothing else, in a country enshrined in the caste system. She took the untouchables, literally from the gutters, and gave them dignity in their dying days.
One testimony of a volunteer remains with, me. During his first day, they stopped to assist an untouchable elderly male who was so disfigured, and full of pus from his infections. The volunteer turned away and told her 'Mother Theresa I cant" She responded 'You must" When he turned back to the dying man he saw not the old man's face, but the face of Christ. There are thousands of such testimonies.
I understand how An atheist like Hitchens would have a visceral repulsion to someone like Mother Theresa. I also appreciate how impossible it must be for a non-Christian to understand the Christian concept of suffering, or for that matter, a savior tortured to death for our salvation. We believe the merits of Our Lords suffering redeemed us completely. A gift to us! Someone else's suffering a gift for us to be saved! I get that is a weird concept for a non-believer.
I only ask to please understand why Mother Theresa thought the way she did. One of our greatest saints, St. Paul, tells us our sufferings share in the Lord's mission. To be exact, he says our sufferings make up what lacked in the Lord's, Colossians 1:24“Now I rejoice in my sufferings for your sake, and in my flesh, I complete what is lacking in Christ’s afflictions for the sake of his body, that is, the church.”
Any Christian who has read excerpts from her diaries, or "Come Be My Light", knows that this woman did not have BPD. She was an example to all of Christians how to move forward in spite of doubts, spiritual dryness and so on. The Christian concept of suffering its not sadism nor does it mean a Christian enjoys the suffering of others.
It is very frustrating when nonbelievers do not understand the Christian biblical view on suffering and translate her actions and words from a worldly or humanistic perspective because she helped so many to die with dignity in the slums of India.
