Some helpful thoughts! Let us not seek a legalistic community where we do not engage with the world, but let us seek understanding so that we be both compassionate and zealous for the truth. I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.

This blog post by Dr. Michael J. Kruger hits on issues of theology, politics, culture, and even the arts (or at least a performer of art). A good and humorous read explaining the importance of the need for a standard of truth over and against subjective claims! As Dr. Kruger mentions, you can find the consistent teaching of the Church laid out in one convenient work of history here. This book sits on my shelf waiting for a good read.
