Scriptures as Evidence

When I was a freshman in high school, an upperclassman on my swim team started a conversation that left me perplexed, given that she was citing scriptural reasons why, in her opinion, my faith did not qualify to reside under the umbrella label of Christianity as hers did.  While this particular incident left me hurt and confused (especially considering my knowledge of the scripture at the time was more focused on the broad details than the specific) what happened was a small example of a common theme in Christian history—utilizing the scriptures to form a personal opinion on how gospel principles should be played out in a church.
