Since last thread got locked before I had time to reply to it I'll add this here:
Quoting the Bible i.e. referencing an outside source to see what is acceptable ethical practice would be the work of extraverted ethics actually - Fe. Introverted ethics is formulating your own ethical stand point as it is a Ji funcion. This is what I meant to say that I have never seen a discussion where you would be defending your own individual ethical judgments as
types would do. Taking on what is collectively considered to be ethical such, as what the Bible says, is expression of Fe.
