During the final episode of her namesake show, Oprah Winfrey credited God for her success and said His grace is something everyone can have "if you let it in."
While Winfrey's lengthy remarks about her beliefs during Wednesday's curtain call of "The Oprah Winfrey Show" drew applause from the audience, many Christians remained skeptical.
"People often ask me what is the secret to the success of this show -- how have we lasted 25 years. I non-jokingly say, 'My team and Jesus,'" Winfrey said. "Because nothing but the hand of God has made this possible for me."
Christians have criticized Oprah for emphasizing spirituality over religion, and using the term "God" when many of her teachings don't align with Christianity.

In the past, Oprah has said she believes there is more than one way to God, which contradicts the Christian foundation. Wednesday, she spoke directly to those who've been critical.
"For all of you who get riled up when I mention God, and want to know which God am I talking about -- I'm talking about the same one you're talking about," Oprah said.
"I'm talking about the Alpha and Omega. The omniscient, the omnipresent, the ultimate consciousness, the source, the force, the all of everything there is, the one and only G-O-D. That's the one I'm talking about," she continued.
In 2009, CBN News spoke with author Josh McDowell, about his then-new book, O God: A Dialogue on Truth and Oprah's Spirituality.
He explained that, although Oprah uses words that sound like they are based in Christianity, her real message is radically different from and even dangerous to the Christian faith.
