You are commanded in scripture to "prove all things" and "despise not prophesyings", and that the "spirits of the prophets are subject to the prophets":

Isa 8:20 To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.
You say "look deeper", means you looked somewhat. Did you find them in harmony with scripture, yes or no? If not, reject, but if so, continue to test and accept that which is from God.
So the question, again, did you test sister Ellen G White, and if so, what was the test, and what did you compare to in scripture. The purpose of this thread is to see if your belief had good reasons (for accepting or rejecting).
A 'pastor' is to be tested like any other. Yet a 'pastor' is not necessarily a 'prophet', are they?
Eph_4:11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;
