I was privileged to lead a men's retreat last week for Christ Presbyterian Church (OPC) in St. Charles, MO. White Horse Inn Producer Shane Rosenthal is a member here (don't count that against the church!) and the pastor is Scott Churnock. This is a solid bunch, and I heartily encourage you to consider worshiping here (or recommending Christ Presbyterian to anyone you may know living in the area).
Thanks to Rev. Churnock and session for your hospitality! I appreciated and enjoyed my time with you all very much!
