Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
Supermarket of Dogmas?
Please don't Bible Thump here, its not like in the Church we don't read the Bible, in fact, each Sunday we have an hour of prayer entirely devoted to the Word called the Liturgy of the Word
Besides of which, I can thump back.
And we heard this voice which came from heaven when we were with Him on the holy mountain. 2 Peter 1:19-21
19 And so we have the prophetic word confirmed,[a] which you do well to heed as a light that shines in a dark place, until the day dawns and the morning star rises in your hearts; 20 knowing this first, that no prophecy of Scripture is of any private interpretation,21 for prophecy never came by the will of man, but holy men of God[c] spoke as they were moved by the Holy Spirit.
Further the Apostle Peter concludes:
speaking in them of these things, in which are some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures. 2 Peter 3:16
Let alone the Apostolic tirade on self-asserting preachers and pastors, be they priests or Protestants alike in 2 Peter 2:1-15
Of course the Scriptures were not the interpretation of the writter. They were written by the inspiration of God. I don't believe the words of Luke because I believe Luke's private interpretation. I believe it because I believe it was inspired by God.
About the Verse about Paul, people used his Scriptures to be sinful, they were twisting he scriptures for lawlessness. Do you consider mainsteam Protestantism sinful and lawless?
Again ,it is all depend all our interpretation. It's all depend on how we interpret 2 Peter 1:19-21.
Protestant interpretation of 2 peter 1:19-21:
This verse means that the Scriptures were never come from the will of the writters. They were written by the inspiration of God. These are the word of God and so a Christian should not interpret them privately. Instead,a Christian should read and interpret the Scriptures with Holy Spirit together. We have to always pray and ask for the help and presence of Holy Spirit when we read the Scriptures. So, this scripture do not against Sola Scriptura.
Orhtoodox interpretation of 2 peter 1:19-21:
This verse means that the Scriptures were never come from the will of the writters. They were written by the inspiration of God. These are the word of God. Men are fallen ,Men's wisdom are very limited and would easily misunderstand the meaning of the Scripture verses. So, man should not interpret them alone and privately. Instead, the whole church, include the past and current church should interpret the bible together under the help of Holy Spirit. The bible should be interpreted with the works of Apostles, Saints, Church Fathers, Life Litugy, etc.
Whether this verse againsts Sola Scriptura,it all depends on how you interpret the above verse. It depends on how you "play" with these word.
I can find that no matter the teachings of Calvinism , Arminianism, Universalism,Lutheran, Charismatic,Wesylan,Jehovah's Witnesses,Seventh-day Adventist,etc, they are all supported by bible verse. Because it all depends on how you interpret the bible. Everybody has good interpretation skill on bible can form a theology easily.
