What is the difference between a preacher and a pastor?

Answer 1

My answer would be this: A preacher is one called by God to go out and preach God's Word to people. A pastor is a preacher who has been called to be a preacher to a church. A pastor has one church that he preaches at and calls his "home" church. A preacher might receive the call to preach, but doesn't stay at one church all the time. He might be a member of a church, but he doesn't necesarrily pastor there. Think of the idea of circuit preachers, moving from town to town.

Answer 2

Pastor means shepherd and is responsible for the leadership of the church. Head pastor leads other pastors and laymen in ministry to the congregation. A preacher is one that gives the sermon and speaks from the pulpit. There are many good pastor/preachers. An example of a preacher that is not a pastor is Billy Graham. He calls people to the Lord then has helpers that lead converts to become "churched." Pastors frequently do not seek the limelight or popularity but have a calling for the smaller church community.
