Oh. Per the AP:
[Gingrich] was a Baptist, but started growing closer to Catholicism after marrying Callista [Bisek] -- a lifelong Roman Catholic [and former Gingrich aide with whom the politician had an affair for years during his second marriage, which you have to admit is at least sort of catholic -- Ed.] -- 10 years ago. He was also inspired by seeing Pope Benedict XVI during his 2008 visit to the United States.
"It was a process which had occurred over about a nine-year period," he said. "I was catching up with what had happened to me, I wasn't making a decision. The decision was sort of unveiling itself."
Ah ha. And so now Gingrich, who has returned to public life as a friend of the Tea Party and is greasing the skids for a likely campaign for elected office of one kind or another, has affirmed his Catholic creds with Nine Days, warming up to a beloved dead pope rather than backing the one still under fire for alleged cover-ups and shielding of abusive priests over the course of 20-plus years as a cardinal. But again, he isn't "making a decision." He's just got continued uncanny timing and historical taste! Jesus Christ, indeed.
