Zion is unity despite differences.
The following experience from my past illustrates this principle:
In one ward I attended long ago, two Gospel Doctrine classes were created - to accommodate the more liberal members and lower the tension in Gospel Doctrine. It was a fiasco, as it only served to polarize the ward officially along ideological lines.
The second class was disbanded, and, instead, various special classes were held - with an intentional mix of perspectives and a direct, clear mandate to listen to all viewpoints and seek to understand the topics as fully as possible. (Elder Wirthlin's analogy of the orchestra would be perfect, but it wasn't around that long ago.) That approach worked amazingly well, as it kind of forced people with different views to listen to each other in a smaller, more controlled environment.
It changed the ward significantly and was a piece of the effort that unified that ward in wonderful ways.
