Final answer:
False, preachers in the antebellum United States did not teach that Americans should change their religion. Therefore, the given statement is False.
Step-by-step explanation:
False, preachers in the antebellum United States did not teach that Americans should change their religion. Instead, there was a religious reform movement known as the Second Great Awakening during this time period.
Calvinism, which taught that only a select few Christians would be saved, lost popularity, and evangelical sects emphasizing the resurrection of Christ and the importance of proselytizing gained influence.
The revival movement preached the equality of all before God, but generally did not challenge the institution of slavery in the South.
