I ran through the article really quickly. It seems like he is basing his arguments on the what certain people said in a one on one interview with Patrick Madrid. From my understanding this book is compiled of chapter long conversion stories.
So I hate to be the bearer of bad news but this guy wasted a lot of time refuting statements that technically had no theological context or arguments presented with them. Dr. Hahn, Dr. Sungenis and Mr. Staples weren’t presenting theological arguments in the book so he isn’t refuting a full picture of their reasoning.
Also the author relies on you allowing him some leeway in order for his argument to work. Like he say…
These definitions point to the meaning of our English word “sufficiency.”
They do? Really? Why? Sure we might use these words interchangeable in our modern English language but that doesn’t mean they have the exact same meaning. Adequate is an adjective that describes a condition of something meeting the minimum requirement, but just barely. Sufficient is a word that describes a condition of being as much as is needed.
Basically him asking for this inch actually gives him a mile.
Finally, what is this adequate for? Every good work. This is talking about being adequate in your moral life. St. Paul isn’t saying scripture supplies us with comprehensive instruction in all matters of Christian doctrine, worship and ecclesial government.
As for the rest of the article it seemed he was more interested in giving his reasons why the Catholic position is wrong and therefor since they are wrong they can’t prove I am wrong.
He really didn’t give an argument to justify his position. So nothing worthy of refuting here.
God Bless
