The actual conversion was brief. It only involved one sentence: “I bear witness that there is no God worthy of worship but God, I bear witness that Mohammed is the messenger of God.”

For 30-year-old Mathew Miller, those words represented the culmination of a long religious transformation from Christianity to Islam.

Miller is a digital media communications major at Middle Tennessee University and works part-time at a golf course. He was raised Christian in California, surfing and dreaming of being a radio DJ.

“My first interaction with Islam was this movie called ‘Not Without my Daughter’. That was my first glimpse into what Western society believed was really going on in Islam,” he said.

"Not Without My Daughter" is a 1991 film in which Sally Field portrays an America woman who flees from Iran with her daughter. The movie, based on true story detailed in a book by the same title, was faulted by critics for portraying a stereotypical view of Iranians and Islam.

But in questioning his own beliefs, and after a conversation with a Muslim friend, Miller’s interest in Islam was piqued.

“I think for the most part I was afraid, don’t really know of what,” he said.

Later, attending Friday prayers at a small Mosque in Murfreesboro, he began to learn more.

“When I put my head on the ground with them, it felt like I could say anything to God, and what I was asking for at the time was guidance. I wanted to know whether what I was doing was the right thing to do.”

His mother had long expected his change of religious faith. “I told my mother I was Muslim in Disneyland. She said ‘I don’t necessarily know if I feel good about it, but if it makes you happy and it’s what you feel is the right way, then there’s nothing I can do.’”

Now he regularly worships at the Islamic Center of Murfreesboro mosque.

Miller, a white convert in a diverse congregation, has heard comments about his faith - and the controversy surrounding his mosque. Once, an Iraqi war veteran told him that the new controversial Islamic Center of Murfreesboro should not be built because it could potentially harbor terrorists.

“I addressed his questions formally and it was funny because at the end of the conversation, he kind of started admitting, 'Well you know, I don’t know anything about Islam.”
