Final answer:
The Christian objection to modernist literature being primarily about its underlying messages is false, as literature is too complex to be reduced to single messages. Also, early Methodists were methodical, Jefferson did use Locke's theories, and not only men participated in the Puritan religion.
Step-by-step explanation:
The assertion that Christians object primarily to the underlying messages rather than the techniques of modernist literature can be considered false. This is because literature is often oversimplified to have 'messages' or 'themes' like Aesop's Fables, with clear-cut morals. However, the reality is that literary works are complex and trying to distill them into single morals or messages negates the multifaceted experience that authors aim to convey. A good example is the interpretation of Sophocles' 'Oedipus the King'. If one were to say the message is 'don't kill your father and marry your mother', they would miss the nuanced points the play is making about human existence and fate. Hence, reducing literature to simplistic messages is not a true reflection of its depth.
Regarding the other quiz statements, the answer to Exercise 6.2.2, which says that early Methodists were called that because they were methodical, is True. It's also True that in the Declaration of Independence, Jefferson primarily used the theories of John Locke, as stated in Exercises 8.1.1 and 'Test Yourself' question 1. Lastly, among the given options about the Puritan religion, the statement that is not true is 'D. Only men could participate', as Puritan women were also involved in church affairs, although they did not hold positions of authority.
