Have thou ever in your mind this seal, which for the present has been lightly touched in my discourse, by way of summary, but shall be stated, should the Lord permit, to the best of my power with the proof from the Scriptures. For concerning the divine and holy mysteries of the Faith, not even a casual statement must be delivered without the Holy Scriptures; nor must we be drawn aside by mere plausibility and artifices of speech. Even to me, who tell you these things, give not absolute credence, unless thou receive the proof of the things which I announce from the Divine Scriptures. For this salvation which we believe depends not on ingenious reasoning , but on demonstration of the Holy Scriptures. (Cyril of Jerusalem, Cat. Lecture 4, Ch. 17)
You belive in Scripture, correct?
Then why don't you believe this?
John 21: (We'll be using the KJV today to keep things on even footing): "And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen."
The Bible Itself declares that it doesn't contain everything.
