This book contains approximately 3,800 words but a powerful subject is addressed within its content. - - - "Can two walk together, except they be agreed?" (Amos 3:3 KJV) From the surface, it sounds very nice and like an event of spiritual peace among these two major denominations, that would be such a wonderful thing to see happen but is it even remotely realistic or achievable? Maybe the more important question would be this: Does God desire for such opposed religious practices to reach a point of saying "Every road leads to God.", when the Holy Scriptures do not at all endorse such a position? Are there actually people knowledgeable in the scriptures that do not recognize how far apart these two belief systems (for lack of a better term), actually are?
In reality, there are no denominations recognized by the Holy Bible but rather those who hold to faith in Jesus Christ are simply called "Christians". With this being the case, this does not take away from the fact that Christians have still been categorized into two major denominations and this has been the case for 100s of years. Still, we have to look at what God's Word has to say, first and foremost; also recognizing that the scriptures themselves state that nothing can supersede or add to God's inspired Words, including anything fallible men believe would better suite them, whether Protestant or Catholic.
