Roman Catholic Unity
In the Roman Catholic Church, which loves to point out the divisions of Protestantism, unity is in many respects more appearance than reality. Within its walls believers and unbelievers are as equally far removed from each other as in many churches of the Reformation. The various orders of the Roman Catholic Church often relate to one another on anything but friendly terms.
