Black Widow

 

 

Natasha Romanova is a longstanding member of The Avengers, better known as "Black Widow." 

She is of Roman Orthodox but is in no way known to be a devout. 

In previous comics there are scenes in which Natasha goes to a Catholic Church for confession. This has risen the question on whether or not she is a Catholic or of Eastern Orthodox. Regardless of which religion she is associated with, Black Widow isn't shown to be devouted to either, an instance of confession doesn't hold much to say she is a strong practicer of religion. 

In addition to her rare protrayls of Eastern Orthodox and Catholicism, Black Widow has reffered to herself as a "godless Soviet." 

Natasha Romanova rarely speaks of her religious affiliations, and whether she is an atheist, a Catholic or of Eastern Orthodox, it's safe to assume she is non-practicing.
