These are helpful questions to keep in mind when you are interpreting Scripture.
1. Do I retain the principle and the practice?
2. Do I retain the principle but modify the practice?
3. Do I abandon/discontinue the principle (and therefore the practice as well)?
“When the plain sense of Scripture makes common sense, seek no other senses; therefore take every word at its primary, ordinary, usual literal meaning unless the facts of the immediate context, studied in the light of related passages and axiomatic and fundamental truths, indicate clearly otherwise.”
