Cultural Christianity has it's foundation on tradition, cultural political ideology, growing up in a church, home school Christianity, or any self-studied dogma of opinions about religious beliefs.
TV shows, Bible college, religious clubs and general political groups based upon God, the Bible and America fall into this category.
Cultural Christianity has zero power from the Holy Spirit that crucifies a man or woman to their sins.
Cultural Christianity does not really hear God's voice impressing upon them to do God's will who is in heaven.
In short, Cultural Christians hear their own voice speaking to them in accordance with their morals, wishes and wills.
