Yes, that is what the 30,000 different Protestant Churches say! The problem here is that Solo-Scriptural is not Scriptural to begin with, Christ gave the authority to Church not a book. If the Church was the ultimate authority back then in determining which books belong "where", under the guidance of the Holy Spirit, then she is the ultimate authority in telling us the correct interpretation and which doctrines is "true or false" based upon on Holy Tradition, correct? You submit to the authority of the Church to tell you what should be included in the Holy Bible, right?
The Church is not the authority but the body. 
Christ is the head of the Church and not tradtion.
The Holy Spirit is the teacher, but he use the Church.
Where do you ever see in scripture that God uses the church? God fills all of His people with the Holy Spirit for all of His true followers are the church the body. It is not a certain sect just claiming they are. God has always used men to speak through His truth. We have the Prophets of old. Then we have His son.. Then we have the Apostles who Christ chose to be His mouths with the gifts and callings that God gave them.
May I ask why is your [and your church] interpretation of Scriptures the correct one? The slogan that goes "I am lead by the Spirit to the truth and thus I do not need men" does not cut it since over 30,000 different Protestant Churches are saying that, and all of them can't be right! You can speak to a Pentecostal or a Baptize or a "non-denominational" and they will all say there have the truth because the Holy Spirit is inside them. Hum...Is God the author of confusion?
This amount you keep putting up has no effect on me. LOL For Jesus sheep know His voice and no other will they follow. He is known By His people because He lives in them through His Spirit.
If the Holy Spirit is the one who teach the Church the truth [and it is He who provide us with the correct interpretation of Scriptures], where is he is now? Is he in the Baptize church? The Pentecostal Church? A "non-denominational" [oxymoron] Church? The Mormons? The Seventh Day Adventist? The List can go on.....
The Holy Spirit abides in all of Christ true sheep. It is written Christ in us the Hope of Glory.
Two reasonable people [Christians] can read Scriptures, and they both will end up having two conflicting understanding of the same book being read, all this with the Holy Spirit! So it is clear that we need the Authority of the Church, for the Spirit teach us through the Church. So who has the correct understanding of Scriptures today since every Protestant Christian is preaching conflicting teachings all based on "Solo-Scriptural"?
The problem is Mamaz is that Scriptures is not your authority but the way you understand a particular Scripture is. In reality, you and other Protestants follow what you believe is the correct interpretation and then you cry "The Holy Spirit lead me to this interpretation; I have the Holy Spirit dude" yet the same guy next to you is a Christian, endowed with the Holy Spirit, and he came with a different conclusion then you. All Protestants claim to follow the same authority, and all Protestants are lead to different conclusions on what a Scripture means. So which conclusions is the correct one Mamaz?
The Bible disproves Solo-Scriptural:
Saint Paul tells the Corinthians, "I commend you because you remember me in everything and maintain the traditions even as I have delivered them to you" (1 Cor. 11:2), and he commands the Thessalonians, "So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter" (2 Thess. 2:15). He even goes so far as to order, "Now we command you, brethren, in the name of our Lord Jesus Christ, that you keep away from any brother who is living in idleness and not in accord with the tradition that you received from us" (2 Thess. 3:6).
Saint Paul told the Early Christians to follow what was written and was not written [those teachings which was passed along by the Holy Apostles that did not make it through written form] in 2 Thes 2:15. So why did Saint Paul told the Early Christians to not to follow what was only written [Scriptures]?
Mamaz, Christ started a Church to preach and guide people. Even Saint Paul said in Ephesians that God gave certain men the ability to teach his word correctly.
The Holy Spirit was sent down on the Apostles on Pentecost, and they were given the charisma to serve and lead the Church. This charisma they passed on to their successors, the Bishops, who in turn passed it on to their own successors, even to this present day [2 Tim 2:2]. The Apostles and the Bibles lead the Church decades before any NT Scriptures written down, and more decades before the Church could agree on what belong in "The Holy Bible". Christ has guided His Church to all truth since the era of the Holy Apostles. Most Christians today what to follow what some 21st Century preacher teach instead of listening to what the Early Church taught in the 1st and 2nd Century.
But who is the Holy Spirit teaching today, since all Protestant Christians are claiming to be lead by the Holy Spirit? The Holy Spirit teach us through the Church, since the Church existed before any NT Scripture was ever written. All Protestant have "continue in His word" and all claim different things, so the real question is who [Bob, John, Liza, Lizzy] is the Holy Spirit teaching today?
Solo-Scriptural has cause more problems than good Mamaz, it has cause more splits in the Body of Christ than the amount of hairs I got in my head.
I do not rely merely on my own interpretation [Like the Ethiopian told St Phillip, how can I understand what I read in the Scriptures unless someone explains them to me?], but the Holy Spirit-filled Tradition of the Living Church from the past 2,000 years. We need to based our understanding of Scriptures on what the Church has taught for the past 2,000 years.
Blessings,
Ramon
P.S: So the ultimate question is Mamaz: Where in the Bible does it teach that one should follow only what was written [Scriptures] (or Solo-Scriptural)?
