The 1701 Act of Settlement prohibits royals from marrying Catholics. Royals may legally wed someone of any faith other than Roman Catholicism—or an Atheist. Meghan is now Anglican and a member of the Church of England after being baptized and confirmed in a secret ceremony at St James’s Palace in London in March. The former actress attended a private Catholic girls’ school as a child, but was raised Protestant.
