Ground Rules: Divine Revelation, Assurance, and Truth

Any good logical argument or discussion generally begins by laying out the assumptions (implicit or not), and in this I will not differ.

• Divine Revelation 
• There is a God, and he chooses to reveal himself through various means. Primarily, this has been done through Sacred Scripture and the incarnation of Christ.
• Assurance
• I believe that the truth can be known with sufficient assurance to live believing ones beliefs with confidence. I do not believe God would reveal himself but leave sufficient doubt to know the fundamentals of the faith. This does however not imply perfect knowledge of every aspect of theology.
• Truth
• There is a God; He has actual views of various topic; He has opinions on various Church practices. This implicitly rejects the modern view of each person finding their own "truth". 
• For example, either God divinely revealed himself in 66, 73, or 76 books. He couldn't have revealed himself exactly in more than one number. 
• Either communion must be symbolic or in some way more than symbolic (Consubstantiation or Transubstantiation).
