According to Wikipedia,
== Local Church offices ==
There are a number of church offices that are elected by the church body as specified by the Church Manual. Positions must be filled by baptised members who attend regularly and the position is held for a 12 month term, except in special circumstances where the church chooses to elect offices once every 24 months. Offices are never elected permanently, although persons may be reelected.
=== Pastor ===
The most prominent church office is that of the [pastor]] or [Minister of religion|minister]]. Adventists believe that pastors are divinely called to ministry and they are ordained by the church for their ministry. The position of church pastor is not elected by the local church, but rather appointed by a local conference.When the minister transferred to the local church for pastor ship he also transfer his membership to that local congregation.Adventist believe in [clerical marriage]] and not a celibate priesthood. In the majority of cases the pastor works with the head elder of the church and is responsible for guiding the church's spiritual direction, chairing the church board and leading out in services.
=== Elder ===
Working with the pastor in the local church is the elder who is appointed by the local church and ordained by the local pastor. The elder is seen as a religious leader in the local church and is able to conduct ordinances. The elder, or elders in some cases (who are led by a "head elder"), is largely responsible for the running of the church and the distribution of responsibility in the church. In the Adventist Church "elder" is not a title. It's a function. The term "pastor" is a function and often used as a title. The "local elder's position authority is limited to the local church he is serving. The "pastor's" authority is universal. The local elder gets his authority from the pastor he is serving under or otherwise from the field administration. The pastor's authority is inherent in his position as pastor.
