What is the meaning of CCC-135? CCC-135:


  The Sacred Scriptures contain the Word of God and, because they are inspired, they are truly the Word of God.


I don't understand the sentence above, because (to me) "contain the Word of God" has a different meaning than "are the Word of God".

Although I will ask how "the application" with the Bible according to the Lutherans, I do agree when this Lutheran link wrote the Bible is the Word of God, not contains the word of God.

My understanding of these terms is as follows:
A. "The Bible is the Word of God" means that all the words written in the Bible are the Words of God.
B. The Bible contains the Word of God = not all the words written (or we read) in the Bible are the Words of God.

Then A can't be also B at the same time (or vice versa)
It must be A if not B ---or--- B if not A.

the Bible contains the Word of God, not is the word of God 
---or--- 
the Bible is the Word of God, not contains the word of God 

Since CCC-135 sentences wrote that A is also B at the same time ---> [(B) The Sacred Scriptures contain the Word of God - (A) The Sacred Scriptures are the Word of God], I am asking how a Catholic would see this as internally consistent. Thank you.
I see your confusion and your syllogism is correct as stated but is based on flawed assumptions. The subtly between 'contain' and 'are' should not be read into as much as you are. Think of it this way: the words contained in the Scripture are the Word of God. The connotation of 'contents' simply refers to where they are represented in one volume or work. It both 'contains' God's literal words (actual words He spoke to Moses, Christ's words while preaching, etc.) and 'is' the Word of God (inspired and directed to be written by God, therefore the possessive connotation). These are not contradictory concepts.

"I am who am" = God's actual spoken words

"In the beginning was the word, and the word was with God, and the word was God" = God's word, spoken and written by a human, inspired or directed to do so by God. So not from His 'mouth' so to speak, but we cannot exactly understand how He works through inspiration, so we have to stop thinking of it like He is dictating things to the authors.
