In the United Methodist Church, Elders are Ordained pastors. Deacons are also ordained clergy. Are you not part of the United Methodist Church, but instead part of another type of Methodist church?
The membership of ordained ministers (elders and deacons) is not held in the local church, but in the Annual Conference.
You are correct in what you told GodsAmbassador2Nicolette, the offices she spoke of are the various ministries fulfilled by the laity of a local congregation. Many other denominations give the title of deacon or elder to special lay leadership positions in their respective congregations. Not so the United Methodist Church. Our ordained clergy are in one of two orders, the Order of Deacons or the Order of Elder. Paragraph 306 of
The Discipline states:
All persons ordained as clergy in The United Methodist Church upon election to full membership in the annual conference shall be members of and participate in an Order appropriate to their election.
Now, to answer your other question. When I was first experienced the sense of being called into ministry, there was no established permament Order of Deacon. Rather we had a two-step process toward becoming an elder, in which a person was first ordained as a deacon with the expectation that it was only a temporary phase (you could only be so ordained for 8 years) before becoming an elder (or dropping out). Then we also had the non-ordained but consecrated status of Diaconial Minister.
The candidacy process was itself meaningless to me. My sense of calling came quite apart from anything that I participated in through the life of the church -- at least not the administrative structures and programs. It was my hands-on involvement in ministry within the church, my personal devotional life, and my Christian fellowship with others that helped me to sense and affirmed my calling. And, yes, I always knew I was called to be an elder because I knew I was called specificaly to pastoral ministry. If you are not sure of where it is you are being called to serve, and only that you are being called to serve it may be that your experience of this process is going to be different than mine. And that is OK. Indeed that is the intention of the Candidacy Process to help you sort through that calling if you don't have a specific sense of it, but only a more general one.
Now, I am tempted go on and even give you a little more of an answer than you have asked for. But the Spirit is gently nudging me to stop. So, I shall listen, and wait to hear if you have other questions.
