on break from ordination studies until Jan - kind of you to inquire
There are few service requirements imposed by the denomination when youve volunteered your services (gratis), and those of your ordained spouse for the past 5 yrs.....
That said - Im not at church right now - Im at work in the family business, cleaning my desk as I will be retiring in the next month or so (at 43) to dedicate my time fully towards ministry. So, technically, Im on my own coin
Besides - freepeing at church would be a misdirection of the tithes and offerings of our congregants.......and frankly a sin.
If thats to what you were implying, drsteve might have better insight, as it was the norm
