Black Friday traditionally rings in the Christmas shopping season.
But this year, the Vatican condemned the spending frenzy in stark terms, calling consumerism a virus.
(SOUNDBITE) (Italian) POPE FRANCIS SAYING: "Dear brothers and sisters, consumerism is a virus that affects the faith at its root, because it makes you believe that life depends only on what you have.
When you live for things, things are never enough, greed grows and other people become obstacles in a race and so one ends up feeling threatened and always dissatisfied and angry.
The level of hatred rises." At a mass in Rome on Sunday, Pope Francis called on the faithful to "resist the blinding lights of consumerism, which will shine everywhere this month" leading up to Christmas Black Friday and Cyber Monday are the biggest shopping days of the year in the U.S. and a growing number of countries in Europe.
According to CNBC, Friday saw $7.4 billion in online sales, up nearly 20% from last year.
