Is the Roman Catholic Church the only true Church?

That shouldn't sound like anything new, that is the age old claim that the Reformers repeatedly denied, and a claim which we deny today as well. The Vatican just released a new document declaring the RCC to be the only true church, and that any church which denies the papacy is not a true church.

Dr. Al Mohler has a good post on the topic so check it out and let me know what you think.
