Priest
Although ministers of pagan religions are mentioned in the Bible, the word priest is most often used of those who attend to activities and things that are devoted to the true God. Today, some Christians refer to their church officials as priests, while others refer to their leaders as pastors.

The two most important Biblical teachings on the subject of priesthood relate to all Christians. First, there is now only one high priest: jesus Christ. Under the Old Covenant, the priest with the highest God-given authority could enter the holiest part of the temple in order to make sacrifices on behalf of all the Israelites. When Jesus sacrificed himself for humanity's sins, he became our eternal high priest. Jesus is the only go-between for us with God. Second, all believers in Jesus Christ are priests who bring their worship to the very throne room of the holy one.
