Below is an article that appeared on an ex-SDA Facebook page. It is about Ellen G White and the belief that she was a prophet. If you substitute her name with Herbert Armstrong's you get the exact same scenario on how HWA claimed to not be a prophet yet deep down thought he was.
"A Crack in the Defense of EGW" (and HWA)
One of the many defenses that the SDA (COG) use for EGW (HWA) is that she (he) "never claimed to be a prophetess (prophet)". But what is a prophet? What are the marks of a prophet? First let's look at what EGW (HWA); the SDA Church (COG) said.
"One of the gifts of the Holy Spirit is prophecy. This gift is an identifying mark of the remnant church and was manifested in the ministry of Ellen G. White (HWA). As the Lord's messenger, her (his) writings are a continuing and authoritative source of truth which provide for the church comfort, guidance, instruction, and correction. They also make clear that the Bible is the standard by which all teaching and experience must be tested."—Fundamental Beliefs, 17
Ellen White (HWA) never assumed the title of prophetess, but she (he) did not object when others called her (him) by that title. (What follows is a quote from EGW, though HWA said the exact same thing) She explained, "Early in my youth I was asked several times, Are you a prophet? I have ever responded, I am the Lord's messenger. I know that many have called me a prophet, but I have made no claim to this title. . . . Why have I not claimed to be a prophet?—Because in these days many who boldly claim that they are prophets are a reproach to the cause of Christ; and because my work includes much more than the word 'prophet' signifies. . . . To claim to be a prophetess is something that I have never done. If others call me by that name, I have no controversy with them. But my work has covered so many lines that I can not call myself other than a messenger." - White, "A Messenger," Review and Herald, July 26, 1906, p. 8. The title "the Lord's messenger" was given by inspiration (ibid.).
And just what did her 'work' entail?
EGW - "Little heed is given to the Bible," she said, therefore "the Lord has given a lesser light to lead men and women to the greater light." - White, "An Open Letter," Review and Herald, Jan. 20, 1903, p. 15 in White, Colporteur Ministry (Mountain View, CA: Pacific Press, 1953), p. 125.
EGW - "'I took the precious Bible and surrounded it with the several Testimonies for the Church, given for the people of God. . . . .You are not familiar with the Scriptures. If you had made God's word your study, with a desire to reach the Bible standard and attain to Christian perfection, you would not have needed the Testimonies. It is because you have neglected to acquaint yourselves with God's inspired Book that He has sought to reach you by simple, direct testimonies, calling your attention to the words of inspiration which you had neglected to obey, and urging you to fashion your lives in accordance with its pure and elevated teachings.'" - White, Testimonies, vol. 5, pp. 664, 665.

5 Christian Science
a : a spiritual seerProphet (Smith's Bible Dictionary)- The ordinary Hebrew word for prophet is nabi, derived from a verb signifying "to bubble forth" like a fountain; hence the word means one who announces or pours forth the declarations of God. The English word comes from the Greek prophetes (profetes), which signifies in classical Greek one who speaks for another, especially one who speaks for a god, and so interprets his will to man; hence its essential meaning is "an interpreter." The use of the word in its modern sense as "one who predicts" is post-classical. The larger sense of interpretation has not, however, been lost. In fact the English word ways been used in a closer sense. The different meanings or shades of meanings in which the abstract noun is employed in Scripture have been drawn out by Locke as follows: "Prophecy comprehends three things: prediction; singing by the dictate of the Spirit; and understanding and explaining the mysterious, hidden sense of Scripture by an immediate illumination and motion of the Spirit."
b : disappearance of material sense before the conscious facts of spiritual Truth
So, we can see by definition, a 'prophet' is a messenger who gives or speaks the message from God. EGW (HWA) did claim to be "the Lord's messenger", so in fact she (he) did claim to be a prophet, by deed, even if not by title. And as such she (he) must be pass the Biblical test of a prophet, and it is in this area that she (he) fails. By God's own word, she (he) is therefor NOT A PROPHET(messenger) SENT BY HIM!!!
