The priest of the home

I was sitting in a summer tent revival meeting.  In such a meeting I was listen to the speaker refer to a husband or father as the priest of the home.  I thought to myself, "Is that a new idea or have I just not been paying attention before."  I could not remember hearing the phrase before.  Later I asked my father-in-law about it.  He affirmed that this was a correct teaching.  I was shocked,  I asked him where such a teaching if found in the Bible.  He went on to tell me about the male requirement of the priesthood Ancient Israel.  I decided I was not in the mood for a hopeless theological debate and let the matter end at my comment that how does that work if in relation to the Biblical teaching of the priesthood of all believers.
