Strange and very defensive reply.
You are amazing at this chameleon routine! You place your entire Faith on Scripture alone! And yet, you cannot define where this book comes from! Did it fall from the sky or was it just handed to you. Is the Gospel of Thomas in it or did Maccabees get struck from it in the Reformation?
You can't define the Canon because it is not in the book you rely on solely for salvation! And Sola Scriptura is not defined as the requisite for salvation in the Bible either!
