The following is a link to a PowerPoint lesson. Many of the points were taken from an article by David Pharr, WHY THE CHURCH OF CHRIST IS DIFFERENT, in the October 2011 Spiritual Sword magazine. I urge you to obtain a copy of this issue and read it. While you are at it go ahead and get a subscription for a full year.
This outline is fairly brief (if you have any questions about the PowerPoint outline please let me know) but I hope all can understand that the church of Christ is indeed different and that is because Christ demands that we be different as we follow his word.
