It is God's Word that is authoritative over your life.
The pastor is simply one voice among many to assist in coming to an understanding of that particular text.
The minister's expositions are only authoritative or binding in those areas where the Scriptures speak definitively.
The pastor should be respected and listened to while in the pulpit if you decide to remain in the congregation where he is preaching in terms of refraining from audible disturbances being enunciated upon hearing something over which you have disagreement.
However, in regards to those issues where they can be a variety of opinion among Christians of similar piety and doctrinal propriety, you are the one that has the final say as to what goes on in your own home and life beyond the church meeting house.
