The two articles are entitled Disagreement is not Disunity and When Disagreements Lead to Disunity. It will not take much of your time to read these two articles, and I think they provide much enlightenment for the church in the midst of disagreements.
It's a fact that people are going to disagree on doctrines and theology. Does this mean that there has to be disunity? While we can remain convinced in our own individual consciences of what we believe, can we not also live "in harmony with one another and in harmony with Jesus Christ"?
A couple of quotes from the articles:
Harmony (unity) with one another and with Jesus Christ does not come through agreement, but through reliance on God and the endurance and encouragement that he provides.
Paul does not say to accept someone if that person understands God in the same way that you do. Instead, Paul says that if God accepts someone, then we are to accept someone. (Romans 15:7)
