Faith and Works

 are like heat and flame, according to Msgr. Pope:

Consider, for a moment, a flame. It has the qualities of heat and light. We can separate the two in our mind, but not in reality. I could never take a knife and divide the heat of the flame from its light. They are so interrelated as to be one reality. Yes, heat and light in a flame are distinguishable theoretically, but they are always together in reality.

This is how it is with faith and works. Faith and works are distinguishable theoretically, but the works of true faith and faith itself are always together in reality. We are not saved by works alone or by faith alone. They are together.
