Wigfield was raised Roman Catholic and today describes herself as a "Sorta Catholic." In a 2017 America magazine piece, she described being Catholic as "not a huge part of my deal... I practice what I call “Chipotle Catholicism”: I go down the line picking and choosing the parts of Catholicism that appeal to me (charity, Pope Frank, spooky stories about saints) in order to create a custom-made spiritual burrito."
