I will start at Revelation 22:16
16 "I Jesus have sent Mine angel to testify unto you these things in the churches. (There are 7 churches) I am the Root and the Offspring of David, and the bright and morning Star." (I guess John did not know about Mary yet.)
17 And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely.
18 For I testify unto every man that heareth the words of the prophecy of this book, IF any man shall add unto these things, God shall add unto him the plagues that are written in this book:
19 And IF any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book."
20 He Which testifeth these things saith, "Surely I come quickly." Amen. Even so, come, Lord Jesus.
21 The grace of our Lord Jesus Christ be with you all. Amen.
Soooo by leaving in this proclamation first recorded by Moses way back on the way to the Promise Land, there can be no claim of ignorance regarding what Sola Scriptures are true and which are willingly rejected.
OK. Serious question here.
How is all that related to the comment that only the Catholic church has the authority tot determine what is Scripture and what is not?
