People commonly believe we can “agree to disagree” and still have unity.
Absolute truth is denied and whatever is true to you may not be for me.
From the standpoint of opinions, there is no problem being united in the midst of disagreement. However, unity at the cost of compromising God’s word is a problem.
Doctrine trumps opinion, and if we disagree, either one of us is right and the other wrong, or we are both wrong. We cannot both be right and disagree on the healthy teaching of the faith.
Leaders must be diligent to stand firm on truth, proclaim it boldly, and follow it explicitly. Then we can be united as God designed for the church.
