Although all Christians, on the basis of the priesthood of all believers, have the right to testify of their Savior, the will of God, however, is not that all Christians should be pastors, but He rather calls people to this office. A person enters the office of the Ministry through a valid call.
Rom. 10:15: How shall they preach except they be sent?
1 Cor. 12:29: Are all teachers?
Heb. 5:4: No man taketh this honor unto himself, but he that is called of God, as was Aaron.
Jer. 23: 21: I have not sent these prophets, yet they ran.
Acts 20:28: Take heed therefore unto yourselves, and to all the flock over which the Holy Ghost hath made you overseers, to feed the Church of God, which he hath purchased with his own blood.
The Lutheran Confessions: “No one should publicly teach in the Church or administer the Sacraments unless he be regularly called” (rite vocatus; Augsburg Confession 14). Luther: “The office of the ministry must be separated from the priesthood of all believers.” (Ps. 110, second explanation, 1538).
