I don't believe that. It's a false flag. Always has been with Gingrich.
Perhaps, but there is this:
From Wikipedia:
A Southern Baptist since graduate school, Gingrich converted to Catholicism, Bisek’s faith, on March 29, 2009.[145] He said “over the course of several years, I gradually became Catholic and then decided one day to accept the faith I had already come to embrace.” The moment when he decided to officially become a Catholic was when he saw Pope Benedict XVI on his visit to the United States in 2008: “Catching a glimpse of Pope Benedict that day, I was struck by the happiness and peacefulness he exuded. The joyful and radiating presence of the Holy Father was a moment of confirmation about the many things I had been thinking and experiencing for several years.”[146] Gingrich has stated that he has developed a greater appreciation for the role of faith in public life following his conversion, and believes that the United States has become too secular. At a 2011 appearance in Columbus, Ohio, he said, “In America, religious belief is being challenged by a cultural elite trying to create a secularized America, in which God is driven out of public life.”[100]
