Whatever truth is not revealed in that Word certainly comports with it...and Rome clearly does not comport with it. Thus, their need to claim to superiority over the Scriptures...
Grace to you...if He allows.
For any fruitful dialog to take place there must be an agreement on the definition of terms, or at lease an understanding of the word usage of the other party. We have failed to establish that common understanding.
The "Word" is not the Bible. The Logos, as used by St. John in his Gospel, represents all order, all knowledge, all truth and all beauty. Allegorically, God spoke creation into existence and to speak and to express an idea a word is associated with the idea and spoken. God's idea of His perfect Self is "The Word" supreme above all other words. It is the second person of the hypostatic union, Jesus.
All knowledge, all order, all truth and all beauty is not contained within the Bible. The Bible is a reflection of the word and much truth can be found within it. Much knowledge, order, truth and beauty is also contained within Sacred Tradition and within natural revelation, science. I have no problem with referring to the Bible as Sacred Scripture", but it is not God or the Logos. Undue veneration or worship of a book is no different that what Catholics are accused of with respect to objects of sacred art, differing only from the printed word in medium.
"Grace to you...if He allows."
Grace is not something given only to the elect or based upon the merit if the recipient. "Grace is favor, the free and undeserved help that God gives us to respond to his call to become children of God, adoptive sons, partakers of the divine nature and of eternal life." Justification results when we cooperate with that Grace and is manifest in the blessings and Fruits of the Holy Spirit in our lives. I am truly blessed.
Peace be with you
