Final answer:
The belief not introduced by John Calvin is: C) Faith revealed by living a righteous life. Calvin emphasized predestination, equality before God, and a strong work ethic but not the idea that faith is solely revealed through a righteous life.So the correct option is C.
Step-by-step explanation:
John Calvin's theology heavily emphasized predestination, the belief that God, in His sovereignty, determines the eternal destiny of individuals.
According to Calvin, God has already chosen who will be saved and who will not, irrespective of human actions or merits.
This concept is complex, involving God's absolute control over salvation.
Regarding the options provided:
A) Calvin did promote a strong work ethic, emphasizing diligence and responsibility in one's vocation as a way to honor God.
B) He strongly advocated for the belief that all humans are equal before God, as everyone stands on the same footing in His eyes.
However, C) Faith being revealed by living a righteous life wasn’t solely introduced by Calvin.
While he highlighted the importance of living a godly life as a reflection of faith, he emphasized that faith itself was a gift from God and not entirely contingent upon righteous actions.
So, the belief not directly introduced by Calvin is the notion that faith is solely revealed through living a righteous life.
So the correct option is C.
