Is the statement 'Mary Stuart ('Mary, Queen of Scots') was a Catholic' true or false?

Mary Stuart, or Mary, Queen of Scots, lived in a turbulent time in British history, particularly during the 16th century when religious tensions between Catholics and Protestants were incredibly high. She was born in 1542 and was raised as a Catholic. This is significant because, at the time, England was shifting towards Protestantism under the Tudor monarchs. Mary's staunch Catholicism heavily influenced her reign in Scotland and her subsequent interactions with England, especially with her cousin, Queen Elizabeth I, who was a Protestant. Mary's claim to the English throne, based on her lineage, was a constant source of conflict, further complicated by her religious beliefs. Ultimately, she was executed in 1587 for plotting against Elizabeth I. So, the statement is true because Mary Stuart was indeed a devout Catholic throughout her life, and this faith played a crucial role in the events that shaped her life and reign.
