I would imagine most Protestant theologians who believe in the Trinity believe that the concept is in scripture.
I am not denying that. What I am saying is that we don't have a statement in the Bible that God is "one Being in three Persons" but that such a statement can be made by looking at the whole of Scripture. The same is with the cessation of the sign gifts and the closing of the canon.
Do you believe in 'sola scriptura'?
Yes, I do believe in sola scriptura:
Here is a good definition of sola Scriptura:
"We reaffirm the inerrant Scripture to be the sole source of written divine revelation,which alone can bind the conscience. The Bible alone teaches all that is necessary for our salvation from sin and is the standard by which all Christian behavior must be measured.
"We deny that any creed, council or individual may bind a Christian's conscience, that the Holy Spirit speaks independently of or contrary to what is set forth in the Bible, or that personal spiritual experience can ever be a vehicle of revelation."-
Cambridge Declaration of Faith, Alliance of Confessing Evangelicals, 1996As for the canon being closed, what is the canon? It is a collection of writings from early apostles and their very close associates that depicts apostolic doctrine, the faith once for all delivered to the saints. Good writings of other men in modern times, even prophetic writings cannot meet these criteria.
I think the burden of proof is on you to show that we still have prophetic writings today. Why do we need more prophesy? What in the Bible is lacking? Didn't the Spirit inspire Paul to write: "All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work" (1 Tim. 3:16-17).
Yes, that was written before the canon was closed, but we already see, in the New Testament, that there were writings that were recognized as Scripture:
2 Peter 3:15-16- "and regard the patience of our Lord as salvation; just as also our beloved brother Paul, according to the wisdom given him, wrote to you, as also in all his letters, speaking in them of these things, in which are some things hard to understand, which the untaught and unstable distort, as they do also the rest of the Scriptures, to their own destruction."- note the words REST OF
1 Timothy 5:18- "For the Scripture says, 'YOU SHALL NOT MUZZLE THE OX WHILE HE IS THRESHING,' and 'The laborer is worthy of his wages.'- the second quotation is Luke 10:7
Again, if you truly believe that prophesy exists today, why not add it to Scripture? Where do you get the idea that it shouldn't be?
