The Bible alone? Is this even Biblical? Sola Scriptura

Here is a good synopsis of the Catholic view: http://www.integratedcatholiclife.org/2015/08/deacon-bickerstaff-the-holy-bible-and-sacred-tradition-comprise-the-word-of-god/ 

Here is a brief excerpt--but the whole article is worth the read and explanation:

 Simply look at the following sequence:

• In prior times, God spoke to us through prophets in varied ways and through a succession of covenants.
• In present times God spoke to us through His Son.
• Divine Revelation was fulfilled, completed and perfected in the person of Jesus Christ, the Word of God. We await no further Divine Revelation.
• Jesus Christ gave this perfected revelation (the Deposit of the Faith) to the apostles.
• The deposit (word of God) has been passed on (transmitted) to us in writing (Sacred Scripture) and oral preaching (Sacred Tradition) from the apostles through their successors (the bishops).
• It is not by scripture alone that we receive God’s word. (cf. 2 Th 2:15)
• The authority to interpret and teach the Word is entrusted to the Church’s Magisterium. (cf. 1 Tim 3:15; Matthew 16; Matthew 18; 2 Peter)
