"When I was growing up I never saw a black person, that was in the early '40s, and that's the same for many areas I know," Potaracke told CNA.
"But I think we accepted (Thea) very well. We loved her dearly, she fit right in with all of us, she always had her singing and her enthusiasm," she said.
"But it must have been terribly hard for her. I think of it now, I didn't think of it then. I didn't think 'Oh, the poor dear, but I think now it had to be a challenge for her, she was in a whole new almost different country so to speak."
According to a biography, Thea's Song, after the newness of the convent experience wore off, Thea experienced culture shock and blatant racism, within and without the convent walls.
Sister Helen Elsbernd, who went through formation with Thea at the FSPA motherhouse, said Sr. Thea didn't mention anything to her fellow sisters about racial discrimination at the time.
"She didn't talk about it. In the early years of formation she tried very hard to fit in with the culture here," Elsbernd recalled.
Her first years as a sister were also challenging for another reason - in 1955, two years into formation, Thea was stricken with tuberculosis, and spent most of that year in the sanatorium.
"I marvel at her constant cheerfulness," one sister wrote to Thea's parents during her illness.
'Black is beautiful': Sr. Thea's racial advocacy grows
Sr. Thea's cheerful energy would remain her signature trait as her passionate advocacy for racial integration in the Catholic Church began to further develop.
Potaracke, who spent time studying with Sr. Thea during graduate school at Catholic University of America, said that for years, the sisters had been going to school at CUA, where they were simply known as the Franciscan sisters from Wisconsin.
That changed when Sr. Thea came on the scene. Early into their days at CUA, Sr. Thea and her fellow sisters attended a student event, during which Thea leapt up to tell her story as a young black woman growing up in the South.
"Thea could just grab an audience any time she wanted, she could just spark life into the group that was in front of her," Potaracke recalled.
"She started singing these songs and everyone was clapping and dancing and jumping around. And after that time we were no longer the FSPA's, it was oh - you're Sister Thea's group. I point that out because that's the impression she made on people," she said.
As a CUA student, Sr. Thea helped to found the National Black Sisters Conference and became a noted public speaker and advocate for African Americans in the Church. She advocated for encounter between white and non-white Catholics, for increased representation in Church leadership for non-whites, and for an embrace of music and traditions from different cultures into the Church.
As her racial advocacy grew, one of Sr. Thea's signature phrases became "black is beautiful."
"'Black is beautiful,' that's what she would say all the time," said Potaracke.
It was a phrase that came from Thea's mother, who had tried to teach her from an early age to handle the racial discrimination that she experienced with love rather than hate.
"Her mother always said that she had to be honest and good to people. Her mother said: 'You can't hate, because if you hate you will become like the people you want to hate. Remember, black is beautiful.'"
An impressive scholar, Sr. Thea would eventually get her doctorate in English, and spent several years teaching at Viterbo College in La Crosse, which was staffed by many FSPA sisters. During her time there, she formed singing groups of African American students who became popular throughout the area, Elsbernd said.
In 1978, Sr. Thea moved back to Mississippi, to help her aging parents and to serve in outreach ministry to non-white communities for the Diocese of Jackson. During this time, she continued to expand her speaking and singing ministries, and travelled extensively to give talks nationally and internationally about the importance of racial awareness and acceptance in the Church.
In 1980, she helped to found the Institute for Black Catholic Studies at Xavier University in New Orleans, where she taught until nearly the end of her life. It was during that time that Fr. Maurice Nutt met Sr. Thea at a conference for black Catholic clergy and religious, at which Sr. Thea was the speaker.
"I was so impressed by her. No one really meets Sr. Thea, they encounter her," Nutt said.
Her talk was the first time that Nutt really considered what it meant to be black and Catholic, and the unique gifts that the black community could bring to the Church, he said.
"It was a cathartic moment for me, because she really enabled me to bring my very best self, my African American self, to the Church, to give my life in service to the Church," Nutt recalled.
He was so moved by her that he joined the next cohort at the Institute.
"She would always say that we are an integral part of the Church, that as African American Catholics, we have gifts to share, we have our spirituality, we have our witness of struggle and suffering. We have the joy of knowing Jesus even in times of sorrow," he said.
"And so what she taught me was to bring my gifts to the Church. She taught me to be very intentional in my expression of spirituality, to share what it means to be black and Catholic, that we should not hide those gifts, but that there's a mutuality, that integration means that you have something to share but I also have something to share."
Nutt remembers Sr. Thea as a brilliant teacher who demanded excellence, but also as a warm and caring woman who embraced her students as her own children.
"Thea became my spiritual mother, and I became her spiritual son, and she would call me son," Nutt said. "She would say that the seminarians she encouraged, she said 'These are the sons that I give to the Church.' And I am so grateful that I was counted in that number."
In 1984, Sr. Thea's parents died within months of each other. Not long after, she received a diagnosis of breast cancer.
"That was crushing," Nutt said. "She was the only child of this elderly couple, it seemed like her whole world had fallen apart, and then she received the challenge of cancer."
While many would be tempted to give up, Sr. Thea made a decision: "I'm going to live until I die," she said.
And she did. She kept up her speaking engagements and outreach ministry at full-bore. She recorded songs and helped compile the African American hymnal "Lead Me, Guide Me", gave numerous biographical interviews including a "60 Minutes" segment, and spoke to the U.S. bishops in 1989.
"We as Church walk together," she told the bishops. "Don't let nobody separate you, that's one thing black folks can teach you, don't let folks divide you. The Church teaches us that the Church is a family, a family of families, and a family that can stay together. And we know that if we do stay together...if we walk and talk and work and play and stand together in Jesus' name we'll be who we say we are, truly Catholic. And we shall overcome - overcome the poverty, overcome the loneliness, overcome the alienation, and build together a holy city, a new Jerusalem, a city set apart where...we love one another."
While she was sick, Nutt said Sr. Thea would pray "that God will heal my body. If God will heal my body, I'll say thank you Lord. But I also know that if God doesn't give me what I ask of him, God will give me something better."
And on March 30, 1990, "that something better was to call her home," Nutt said.
The legacy of Sr. Thea
Nutt said he thinks Sr. Thea will be remembered for her passionate advocacy on behalf of blacks and other minorities in the Church.
"She spoke about the fact that African American Catholics, we have a deep and abiding history. She told the history that we come from the Ethiopian eunuch, we come from Simon of Cyrene...that we are not late in joining the Church but that people of African descent have been there from the early days of Catholicism, and that this is our home," he said.
Potaracke said she remembers Thea as a warm woman who had a strong sense of self and wasn't afraid to advocate for herself and others.
"She was a spark, and she spoke her voice, if she didn't like something she said it strong and clear, no matter what meeting you were at, she would speak her voice," Potaracke said.
"It was her inner belief that she was a beautiful woman, that she had a place in this world, and that she was going to go out and change the people she met, and she did. Whether you were penniless or whether you were the wealthiest person, she just had lots of friends in every corner of the world."
He said he believed she would also be remembered for her love of God, from which flowed her joy and love for others.
"You knew in her midst that you were in the presence of someone extremely special, who had a deep connection with God. Thea said she grew up in a world where God was so alive, and she shared that joy with everyone, that God is real, that God is love, that God is alive, and anyone who met her experienced the presence of God," he said.
As for Sr. Thea herself, she once said that she wanted to be remembered simply as someone who tried.
"Think of all the great things she did, and she simply said: I want to be remembered as someone who tried. She said she wanted on her tombstone: 'She tried,'" Nutt said.
"That speaks of her humility. That speaks of her love for God and that she never proclaimed herself to be holy or righteous. She was a disciple of Jesus Christ who tried to love one another, to love other people, to try to lift her service to God and the Church."
Nutt encouraged Catholics to ask for Sr. Thea's intercession as her cause gets underway.
"I would encourage people to seek her intercession, especially if they're struggling with their faith, if they're struggling with family issues. I would encourage students to pray to her when they're taking tests, I would also say anyone battling cancer of any kind to seek her encouragement, to seek her inspiration, as they journey through their battle with cancer."
As is customary, when a bishop begins the preliminary phases of someone's cause for canonization, the cause must be put to a vote of the U.S. bishop's conference. At their meeting Nov. 12-14, the bishops are expected to endorse the opening of the cause of Sr. Thea Bowman, which is being overseen by Bishop Joseph Kopacz of Jackson.
