I want to know the answer to the following question:
What was the court seeking, in using Jefferson's letter?
All the background I'm provided with is that "Writing for the majority, Justice Stephen Johnson Field cited Jefferson's Letter to the Danbury Baptists to state that "Congress was deprived of all legislative power over mere opinion, but was left free to reach actions which were in violation of social duties or subversive of good order."". Is that enough to answer the question?
Answer: no
