A little bit late here. I’m a seminary graduate, too! I just went because God told me to. -twice. I didn’t obey God the first time, and a lot of bad things happened to me. I didn’t go, because I thought I heard God wrong, because a woman can’t become a preacher. Little did I realize there were many purposes for getting a seminary degree. An MDiv, specifically. One is to be able to correctly read the bible, esp. using the original languages. Another was to get tools for ministry. It’s kind of ironical, that within a few years of starting to attend a very conservative seminary, God moved me into leadership roles. But, had God not supplied me with the tools, in seminary, I could not have done that work. I have always run various Internet forums. Currently, I run a group of 4200 people with Rheumatoid Arthritis. It’s a disease I also have.
You may wonder what it has to do with serving Christ, but it is pre-evangelism. And many times evangelism. It is also to comfort, encourage and help the sick; and the poor, as many people who get sick lose their jobs, and become poor. People trust me in my leadership role, especially my admin/mod team. They know I will do the right thing to protect people, and help them through what is a very dark valley, getting a painful and debilitating disease. In other words I am ethical and that comes out of my faith in Christ. It is a mission field for me. I have many people who are friends, from a variety of world religions, and they get a lot of bible verses, and stories about how Christ has helped me. Not everyone gets saved, but as long as everyone hears the gospel clearly, I hope I am obedient to God.
As far as ordination, I think it really depends upon your denomination. I am currently working on a PhD in Disability Theology. Not sure if I will finish, because my physical limitations are increasing. But, one of my goals is to write a book outlining how to reach people with the gospel for Christ, through various disabilities and issues on the internet. I don’t have cancer, for example, but someone who has might become very effective, even during chemo and all the invasive procedures cancer patients go through, with some direction as to how to not just model being a Christian, but how to effectively be a missionary. To that end, I pursued ordination through the denomination of the church I currently attend, a small Baptist denomination. But, their rule is that you must be employed by the denomination and doing ministry to be ordained. I filled out all the papers, but my health would never allow me to become even a part time pastor within the denomination. At one point, when I was healthier, I was hoping to become a chaplain. But, according to my denomination, they would not ordain me if I was in Lutheran long term care, for example.
Other denominations have different rules. Some denominations ordain you once, and it stays with you forever. I heard of strange cases in the Church of the Nazarene, which would ordain couples. If the wife died, for example, the husband would lose his ordination, even if he was still pastoring the same church. Then, the denomination would remove him from that church. It seems like a really odd process. Your beloved spouse that you have ministered with for many years dies, and you not only lose your spouse, but your church and your ordination.
In quite a few denominations, a person is ordained, and then keeps that ordination till they die. It sounds like that is what you are looking for? The strange thing about my Baptist denomination, is that the pastor who was there when we originally started attending was ordained in the second year. His father, also a Baptist preacher, came from England to participate in his ordination. It was quite a big deal. Then, the pastor resigned because of severe depression. He was a fantastic preacher, but could not handle the administrative side of the church, even with a whole team of elders supporting him. And they really supported him. He tried to get on staff in another church with the same denomination, but they needed a children’s pastor, not a preaching pastor. So he did not get on staff, and works a secular IT job. But I know for a fact, he has never had his ordination revoked. Not that it should be! But, I read the bylaws of the denomination, and it should have been revoked. I disagree with that. Although I can see why some people might feel that someone not employed by the denomination is no longer answerable to that denomination, and therefore should not be able to carry on as an ordained pastor. Plus, I remember they had a bunch of levels of ordination, which also seemed a bit weird to me. A part time pastor is less ordained than a full one. Our current assistant pastor is in the process of getting ordained. But, she will be a less ordained person than the senior pastor. This is not about men versus women. If she was a man, it would be the same. In fact, the senior pastor has become a complete heretic, (an open theologist) whereas the woman assistant has very orthodox theology, and preaches better than the pastor. But, even if she was a man, she would be considered less. And he was also ordained, quit and worked a secular job for a few years, then came back. But his was a crisis of faith. His faith is not orthodox, although when he was ordained, it was. So, should someone who does not hold to the basic theology of the denomination be allowed to continue as senior pastor, and stay ordained and sanctioned? A difficult question. I have no patience with heresy, and this is major - he does not believe in the sovereignty of God. He thinks we chart our own course, and God has very little to do with our lives.
But enough of my complaints and puzzlement. In seminary, the women students often discussed ordination, which was forbidden in our denomination. Except, ordination was church based in that denomination, and there were quite a few women who had been ordained, although the leadership liked to pretend it was not happening. (I don’t really care what anyone thinks about women in the pulpit, that’s a different thread! Or check some of the old ones, it’s been discussed to death in this forum!) Anyway, one of the women had a very interesting take on ordination. She was actually part of the staff on a large church within the denomination. She had a counselling degree, and was certified as professional counsellor by some kind of gov’t standard. So, she was on staff, being paid, and she did preach from time to time. But, she did not want to be ordained. She did a position paper for theology class that no one should be ordained. I never read the paper, but she did a lot of research into the whole issue. And her church would have ordained her. But, she did not become ordained, and she was one of the most irenic, God -loving people I have ever met.
Anyway, I think you are asking the wrong people. You need to talk to your senior leaders and denomination about ordination, not us. I can give you examples about this all day long. But if you are not in the denomination I attend, it means nothing to you. Let us know what you decide to do. And do stay in ministry. God has obviously called you to vocational ministry, (meaning, you sound like you have an heart for God!) and I hope you get the support you need!
