Preacher and pastor are two different terms that are usually used in the Christian faith, even interchangeably. They can be correct when used interchangeably sometimes, and can still be wrong sometimes. This is simply because a pastor can also be referred to as a preacher, while a preacher might not necessarily be a pastor. Preachers generally are those who take the word of God to people; that is, they usually preach in different places. A preacher might not necessarily own a church or be in charge of a church.
Conversely, a pastor is known to be in charge of a congregation -a church. Relatively, the pastor means shepherd, whereas the members of the church are religiously referred to as flocks. Hence, a pastor is considered to teach, guide, and put the members of the church through different aspects of life. In addition, a pastor usually functions as the administrator of a church, while a preacher does not necessarily administer a church.
