This is a Message Board Post that is gatewayed to this mailing list.

I looked up some history on Rev. Bergen who has a park named after him in Springfield, IL. He was the first pastor of 1st Pres in Springfield. Go to their website (http://www.first-pres-church.org/), if you haven't already, to find more info on him. There's an excellent and must-read article about him in their March 2003 newsletter. You could also email that church and ask what OSP means!
