The term "Christian" is now used to distinguish a person who is not a "Catholic." But usually what it means is that person is no longer attending a "Catholic" Mass or is no longer doing what "Catholics" do (e.g. pray the rosary, pray to Mary or the saints, etc.). But, other than that, what is the true difference between the two? It has nothing to do with externals. In fact, it has nothing to do with labels. It has everything to do with how the Gospel has impacted their lives.
