Pro-abortion clergy????
No such thing.
You can be pro-abortion. Or you can be Clergy. You can’t be both.
You can nowadays. There are denominations that provide abortion-on-demand as part of employees' health care packages (like ELCA). Some denominations even support hospitals that do 'regular' abortions, like here (note UCC): http://www.nrlc.org/news/1999/NRL1199/illi.html
