The teaching that most aligns with the spirit of the Second Great Awakening's impact on attitudes towards slavery is D) All enslaved people should be emancipated immediately.The Second Great Awakening, which started in the 1790s and gained momentum by the 1820s, heavily emphasized that salvation was available to all people regardless of their social status, and that everyone was equal before God. This religious revival led to heightened moral responsibility and societal reform aspiration, including the forceful moral argument against slavery by many abolitionists.
