What are the key differences between a priest, a pastor, and a preacher in terms of their roles and responsibilities within a religious community?

A priest is typically a religious leader in the Catholic or Orthodox tradition who performs sacraments and administers the church. A pastor is a leader in Protestant churches who provides spiritual guidance and oversees the congregation. A preacher is someone who delivers sermons or teachings, which can be done by both priests and pastors. Each has a unique role within their religious community, with specific duties and responsibilities based on their denomination.
