The Streets of Calcutta
During the next two years, Teresa pursued every avenue to follow what she never doubted was the direction God was pointing her. She was to give up even Loreto where I was very happy and to go out in the streets. I heard the call to give up all and follow Christ into the slums to serve him among the poorest of the poor.
Technicalities and practicalities abounded. She had to be released formally, not from her perpetual vows, but from living within the convents of the Sisters of Loreto. She had to confront the Church's resistance to forming new religious communities, and receive permission from the Archbishop of Calcutta to serve the poor openly on the streets. She had to figure out how to live and work on the streets, without the safety and comfort of the convent. As for clothing, Teresa decided she would set aside the habit she had worn during her years as a Loreto sister and wear the ordinary dress of an Indian woman a plain white sari and sandals.
Teresa first went to Patna for a few months to prepare for her future work by taking a nursing course. In 1948 she received permission from Pius XII to leave her community and live as an independent nun. So back to Calcutta she went and found a small hovel to rent to begin her new undertaking.
Wisely, she thought to start by teaching the children of the slums, an endeavor she knew well. Though she had no proper equipment, she made use of what was available writing in the dirt. She strove to make the children of the poor literate, to teach them basic hygiene. As they grew to know her, she gradually began visiting the poor and ill in their families and others all crowded together in the surrounding squalid shacks, inquiring about their needs.
Teresa found a never-ending stream of human needs in the poor she met, and frequently was exhausted. Despite the weariness of her days she never omitted her prayer, finding it the source of support, strength and blessing for all her ministry.
