Whenever I get depressed about doctrinal debates between Christians I like to watch videos of underground churches which are persecuted.
A video of underground churches in China:

Here's a testimony of Christian persecution in North Korea, believers are so desperate that they meet in secret in pit toilets in the prison camp:

In such an environment of persecution denominational differences simply have no room to form. Out of desperation the church is driven to love Jesus with all their heart, soul and mind in unity and to live and hang on every word that comes from the Creator of the universe.
If any of you are touched by these testimonies, here are two good Christian organizations I know of that support persecuted Christians around the world:
