OK, now you really have my attention.
So...it's all a bit scary, and a bit exciting, and a bit confusing. It also makes no logical sense
That is the way it should be. If your goal is to keep your curent job and serve a small church part time, then Licensure may be the way to go, as long as you realize you will always be pegged here without the seminary education. A good program of reading and good mentorship from a respected pastor in the conference is enough to get you started.
Please remember that a call to ministry always starts with the affirmation of your local church. If they are acknowledging your leadership abilities, and are willing to support your call, then this is a great start.
Have you preached at your local church and neighorbing churches when they needed filled pulpits? I started preaching about once a month when I was in college. (I can't say that I was any good at it until after seminary and a few more years of experience.) But Preaching 4 to 8 times a year and carefully gathering feedback, will help give you a sense if God is leading you in this direction. Lay people often have a good sense as to who will become good pastors, if you seek their advice and wisdom.
Bangor Theological Seminary I believe still has a web baised program for people in your position, if you want to move beyond part-time ministry.
