The only reason I was brought to this post was the quotations aroundcompassionate.
Compassion: sympathetic pity and concern for the sufferings or misfortunes of others.
No where in any definition I see does it require a deity or religious practice in order for this to be effective or a quality of nurse. We come into the field because we are called to, regardless of our religion. Understanding Atheism, and even other religions, is KEY to understanding how to provide the best care for friends, families, strangers, patients, etc.
Without this understanding and acceptance, intolerance and hatred grows. Which only ostracizes everyone here, in the workplace, and anywhere else they can feel tension. Hostile attitudes are toxic, be sure you aren't the one that's the problem.
