Are the writings of Ellen G. White inspired by God in the same or similar sense that the Bible is inspired by God?

"The apostle (Paul) cautioned the Thessalonians not to despise the gift of prophecy, and in the words, “Quench not the Spirit; despise not prophesyings; prove all things; hold fast that which is good,” he enjoined a careful discrimination in distinguishing the false from the true. He besought them to “abstain from all appearance of evil;” and closed his letter with the prayer that God would sanctify them wholly, that in “Spirit and soul and body” they might “be preserved blameless unto the coming of our Lord Jesus Christ. Faithful is He that calleth you,” he added, “who also will do it.” {AA 263.3}

"But the scriptures, while foretelling this dreadful apostasy, also plainly teach that just before the second coming of Christ, many will be rescued from the darkness of error and superstition. Once more the earth is to be lightened by the glory of God. The pure truths of the Bible are to shine forth. And in this time of heavenly illumination marking the approaching end of the age, the gifts of the Spirit are again to be manifest in the true church. “It shall come to pass in the last days, saith God, I will pour out of My Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams: and on My servants and on My handmaidens I will pour out in those days of My Spirit; and they shall prophesy.” Acts 2:17, 18; Joel 2:28, 29. {CET 242.2}
In clear terms the prophet John speaks of “the remnant,” or the last church, as those who “keep the commandments of God, and have the testimony of Jesus Christ.” Revelation 12:17. In another passage the same writer gives a plain definition of what he means by the “testimony of Jesus.” When on one occasion John attempted to worship the angel who appeared to him in vision, the angel said: {CET 242.3}
“See thou do it not: I am thy fellow servant, and of thy brethren that have the testimony of Jesus: worship God.” Revelation 19:10. {CET 243.1}
Under similar circumstances the same angel said, as recorded in another place: {CET 243.2}
“See thou do it not: for I am thy fellow servant, and of thy brethren the prophets.” Revelation 22:9. {CET 243.3}
The thought expressed is the same in both these passages. In one, however, John’s “brethren” are said to have “the testimony of Jesus;” in the other these “brethren” are called “the prophets.” {CET 243.4}
Therefore it is the prophets who have “the testimony of Jesus;” and the angel who appeared to John is evidently the special messenger who conveys instruction to all the prophets,—doubtless the angel Gabriel, who is mentioned as having appeared to Daniel. See Daniel 8:16; 9:21. The same angel further said to John, “the testimony of Jesus is the Spirit of prophecy.” Revelation 19:10. {CET 243.5}
Comparing the Bible expression, “the testimony of Jesus,” with the statement of Revelation 12:17 concerning the “remnant ... which keep the commandments of God, and have the testimony of Jesus Christ,” we conclude that prior to Christ’s second coming His true church will be keeping His commandments, and that they will have the Spirit of prophecy. {CET 243.6}
The rapid fulfillment of the predictions of Holy Scripture regarding the signs and events which were to mark the closing scenes of earth’s history, is a sure evidence that we are now living in the last days. Therefore a company of Christian people who keep the commandments of God and who have the testimony of Jesus Christ—the Spirit of prophecy—should today be in existence. Where may they be found? {CET 243.7}

Our church must have the Spirit of Prophecy or it is not God's true end time church.

When God spoke to Samuel was it any diffent from Elijah or Isaiah, but every man has to let the Holy Spirit guide them on this, it cannot be proven by force of text.

Yes let every man who has the Holy Spirit guide them in this, BUT it has to be proven by the word of God which came through men.

I they speak not according to this word then there is no light in them.

The force of the text is in God's word which is the ONLY way to prove the Spirit.

Basically, since all messengers of God were verbally inspired, and it is by personal conviction that it is recognised, so that's how we assemble for worship of Jesus as a church: personal conviction.

Yes, we can explain it, but we are personally convicted by the Spirit of Jesus.

Yes Brother, but we have the Spirit of Prophecy that will PROVE who has truly been convicted by the Spirit.

When those who have been spreading lies see the fulfillment of the prophecies those who were truly entrusted with deep truth come to pass, then they will know they were deceived and their knees will knock, and their bowls be loosed.

We have a sure word of prophecy. When the fulfillment of what the true SDA Church has been proclaiming comes true it will also further strengthen our faith in those words to sustain us through what we know will come next.

What do you mean by "verbally inspired"?
Do you believe they sat down with quill and parchment and then God dictated the message word for word as they wrote it down?

The different styles of writing by the different Biblical authors show that was not the case.

As to testing the prophets, James is correct, it must be tested by scripture and be in agreement. Simply relying on our senses is not enough.

Even Jesus, instead of dazzeling the disciples with His brightness, took them through scriptures, from Moses through all the prophets to show them the mission of the Messiah (See Luke 24:27)
And Paul praised the Bereans as being noble, for they checked out what he said by comparing it with scripture. (Acts 17:11)

Yes, exactly dedication.

But I think Colin was trying put into words something that is hard to explain.

The men of God were brought into scripture by so many different paths, but it is safe to say they were all inspired by the holy Spirit through the angel of prophecy.

Gabriel is constantly seen talking to his brethren the prophets in scripture.

Then what happens usually is they go on about their lives and then miraculous things happen associated with what God had told them and He inspires them to write these things so it becomes practical for use by others in their experiment of faith.

Moses listened to God at the burning bush then used the information verbally to other leaders for Israel, and some of it was written down immediately and placed next to the ark, and some eventually got written down, but it was not for many years. The Holy Spirit preserved the stories and brought it to mind perfectly while he was writing. Same with the Apostles, God inspired them exactly what to write through life experience.

I don't believe that the bible was inspired of God. However, I do believe that men were inspired of God to write books and those books can be found in the bible. Jesus tells us Himself that Moses wrote of Him thus proving inspiration. I do not believe that everyone who wrote letters which were chosen by men to become a part of the New Testament were inspired of God. Jesus never promised us a book with nothing but the truth in it. He did promise us that the Holy Spirit would guide us into all truth and that those with Wisdom would understand.

Neither do I believe that Ellen White was inspired by God or His Holy Spirit. God sent His Son into this world to tell us the Truth (John 18:37) and the Truth is good enough for me. What has Ellen White told us that Jesus Christ did not? Should we teach others information that Jesus never taught?

Jesus provided eyewitnesses to His ministry on earth and if anyone claims to speak to or for Jesus other than what has been provided by those who followed Him while He was in the world we need to weigh their words with the Word which was made flesh to prove them True.

God has preserved His word perfectly and He brought the most inspired perfectly balanced elements of His faith together in the 66 books.

Even the flaws in that book were ordained by God.
