Jesus Christ established the foundation of the Christian church with various callings and priesthood offices such as apostles, prophets, pastors, teachers and evangelists (Eph. 4: 11). While the New Testament does give some important information about the duties and relationship of these offices, Joseph Smith and the LDS church benefit from modern revelation which clarifies the operation of these callings in the Church of Jesus Christ today.
For, since ye are subject to the bishop as to Jesus Christ, ye appear to me to live not after the manner of men, but according to JesusChrist, who died for us, in order, by believing in His death, ye may escape from death. It is therefore necessary that, as ye indeed do, so without the bishop ye should do nothing, but should also be subject to the presbytery, as to the apostle of Jesus Christ, who is our hope, in whom, if we live, we shall [at last] be found. It is fitting also that the deacons, as being [the ministers] of the mysteries of Jesus Christ, should in every respect be pleasing to all. For they are not ministers of meat and drink, but servants of the Church of God. They are bound, therefore, to avoid all grounds of accusation [against them], as they would do fire.
1 Clement 17 Quotes Isa. 60:17 "For thus saith the Scripture in a certain place, "I will appoint their bishops in righteousness, and their deacons in faith."
The Epistle of Ignatius to the Trallians Chapter III "In like manner, let all reverence the deacons as an appointment of Jesus Christ, and the bishop as Jesus Christ, who is the Son of the Father, and the presbyters as the sanhedrim of God, and assembly of the apostles. Apart from these, there is no Church."
The Epistle of Ignatius to the Smyrnaeans Chapter VIII "Let no man do anything connected with the Church without the bishop. Let that be deemed a proper Eucharist, which is [administered] either by the bishop, or by one to whom he has entrusted it. . . It is not lawful without the bishop either to baptize, or to offer, or to present sacrifice, or to celebrate a love-feast. But that which seems good to him, is also well-pleasing to God, that everything ye do may be secure and valid."
