Bringing it up when talking apologetics... Someone gave a great example about other associations a person could belong to, and their rules etc, but this concept almost always goes over peeps heads for various reasons. I think the heart of the matter is that the idea of a church having some kind of power to make laws is so foreign to most Christians today (with good reason, they are all "feel your way through the gospels" led) that they refuse (refuse) to even consider the idea.
The problem is, indeed, as you note, the concept that a Church has any authority. The Freemasonic view, which is simply how life is seen by the great majority of people today (in the West, anyway) is that religion is for Sunday. Religion is fine but must be confined to personal beliefs and cannot truly form one's ideas, life, actions, or anything else
outside of the church building on Sunday.
It is most frustrating to talk with an individual who, after discussion clearly shows he is factually wrong on some issue, say, "Well, we'll just have to agree to disagree," or, "Well, that might be true for you but it's not true for me." Such comments are perfectly acceptable when discussing personal opinions (e.g., whether on thinks baseball is more or less exciting that football), but not about facts (e.g., the very existence of God).
Many of the apologetics of the past simply don't work today because so many people simply cannot grasp the concept that mutually exclusive "truths" cannot both be true. When it comes to the issue of religion, the concept of "religious liberty" is so ingrained upon the Western psyche that it is very difficult to convince a person that his liberty is not absolute. People cannot grasp the concept that his liberty only a choice between accepting or rejecting the True God and that any exercise in his liberty that is contrary to the commands of the True God is an absolute rejection of Him.
Until one can punch a hole through that bubble that surrounds most people's intellect so that he can really see that they've swallowed, hook, line, and sinker, the Orwellian doctrine of Double Think, it is futile to argue doctrine and morality. The fact that people today can read Orwell's
1984 and imagine it a good story that has no relevance to the way they think is most disturbing. Why God gives a few of us the grace to see while the vast majority are blind is truly a mystery, but one should always thank Him for giving that most singular grace.
