Who does that? The Church wrote what was dictated. She then gave it to you. She could have written what she wished to write, and told you that it's from God, and you would be o wiser. So you still have to put your trust in the Church when you believe the scripture.
"She" did not give me anything. It is God himself that has revealed his truths to mankind and seen that these truths have been preserved for all. Constantly taking credit for your religion as "The Church" is simply false, expected, but false. The reason is simply the fact that God revealed his truths to mankind long before there ever was a formal "church". Going by your logic, the Catholic Church can claim credit for writing the Old Testament as well because that is also Holy Scripture. Now if you are willing to agree that all those who are in Christ are members of the one body, the church (notice the lower case "c"), and accept that even those who believed during the time before Christ came are also part of this universal body, then I will accept that the church was endowed with the knowledge of God's truths, certain ones were inspired to record those truths for posterity and they as a whole, through the power of God ensured these recorded truths were preserved for all mankind. Do we have a deal?
The Catholic Church has indeed written what she wished and has passed it off as if it is from God over these many years. It is called "Holy Tradition". This has served "her" well in that her followers have been told that whatever "she" tells them it is as if God himself said it. Acceptance of it all is made mandatory if the members expect the "beatific vision" (heaven for us normal folks). You can certainly believe all that to your hearts content, but please spare us the condescending "you will be the wiser" advice. I KNOW where my faith lies - the source.
