You shouldn’t be looking for a Christian interpretation, you should be looking for a Bible interpretation. The Bible defines its own terms within the text in the same way that a legal document defines the terms within itself. What you say doesn’t make sense as any valid Christian interpretation should stem from what the Bible says. If you’re going to use extra biblical texts they must not contradict what exists in the Bible and they can’t base any theories off of definitions for words that the Bible doesn’t provide.
