The public ministry and the Bible

From what I have heard regarding the office of the holy ministry, the three distinctive functions of the ministry are preaching, administering sacraments, and exercising the Office of the Keys. Is this correct? If so, could you explain where in the Bible these three functions are described as exclusive to the ministry? Thank you.

The Shepherd Under Christ, a textbook for practical theology, addresses your questions well. It explains, from Scripture, to our seminary students how the public ministry relates to the universal priesthood of believers.

“God has given the gospel to all Christians, individually and collectively. Jesus entrusted to each Christian and to groups of Christians gathered about the gospel the right to bind or loose, to forgive or retain sins, by declaring or withholding His gospel (Mt 18:18; Jn 20:21-23). Every Christian as a member of the royal priesthood has been called to proclaim the Lord’s praises (1 Pe 2:9). He is called to function as a witness and servant of His Lord, as a light to the world (Mt 5:16). He has this call as a member of the universal priesthood of all believers. This is the ministry that Christ has enjoined on His New Testament church and that has been committed to every Christian (Mt 28:18-20; Mk 16:15).

“The Lord has also established the public ministry in His church. This ministry does not set up a priestly caste apart from the laity, for, as noted above, all Christians are priests of God. The difference lies in the word public. The public ministry is a service performed in the church, in behalf of fellow Christians, in their name. Like the public official in a state who functions in the name of his fellow citizens that have elected him, so the minister has an office in which he carries out responsibilities that have been entrusted to him by fellow Christians. These responsibilities are not essentially different from those Christ committed to every Christian. The minister too is to serve in the gospel as did Paul and Timothy (Ph 2:19-23); to labor in the Word and doctrine (1 Tm 5:17); to speak the Word of God (He 11:17). But the minister does this in the church, in behalf of the church, and as a representative of the church.

“While every Christian has the call to proclaim Christ to the world, for the public ministry, and this includes the pastoral office, a specific call is necessary. Within the church every Christian, being a priest of God, possesses the ministry in equal measure. Good order, therefore, requires that no one function publicly, that is, in behalf of the assembly of Christians, unless these Christians themselves by means of a call have commissioned him to do so (1 Cor 14:40; Ro 10:15; 1 Pe 4:15).

Praise God for the gospel ministry he has entrusted to all Christians. Praise God for those who are called to labor in their behalf.
