Whether they accept it or not Protestants relied on the authority of the Catholic Church to know which scriptures are part of the Canon of Sacred Scriptures, and which are not. If it weren’t for the Catholic Church we would not have our Bibles today.
In 382 A.D Pope Damasus gathered the bishops in Rome in order to form the Canon of Sacred Scriptures which includes the Old and New Testament.
The following is the decree of the Roman Synod concerning the Canon of Scripture.
Acts of the Roman Synod, 382 A.D
Likewise it has been saud: Now indeed we must treat of the divine Scriptures, what the universal Catholic CHurch accepts and what she ought to shun.

The facts of history regarding the origin of the Canon of Sacred Scriptures cannot be twisted, tainted or revised. The Sacred Scriptures did not fall down from heaven whole and intact nor was it compiled by the aposltes themselves.
The Catholic Church is solely responsible for compiling the canon of Scriptures in 383 A.D in the Synod of Rome. During this time no Protestant denomination ever existed yet, thus they cannot claim of having any hand in the formation of the canon of Sacred Scriptures.
