In the ten-part fictional TV series, created by the Oscar winning The Great Beauty, famed Paolo Sorrentino, the British actor plays the 'troubled and conflicted' Pope Pius XIII, which is set to air on Sky Atlantic later this month.
Law told Radio Times, that he did consider whether it would cause offence but decided the series was not a critique of the religion.
“I'm sure someone somewhere is going to be offended by it, but that's what storytelling is about. Opening discussions, openly, freely and diplomatically... I'm all for that,” said Law.
The show follows the ascent of Lenny Belardo to the head of the Catholic Church - a young, chain-smoking, Cherry Coke-swilling Pope struggling with responsibilities.
“It's not The West Wing in the Vatican,” said the 43-year old actor, when asked about the show's message.
“The themes are more about how an individual survives one's relationship with faith - as opposed to accurately portraying Vatican politics” he added.
The Young Pope premieres on Sky Atlantic, on October 27.
