And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand, The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation;...Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus....He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still.
Revelation 14:9,10,12/22:11
"A serious question arose in the minds of some who heard the message of Righteousness by Faith presented at the Minneapolis Conference, as to the relation that message bore to the third angel's message.
In their perplexity, a number wrote to Mrs. E. G. White for an 
expression of her views on this question. Regarding this inquiry and her reply, we have her published statement, as follows: "Several have written to me,inquiring if the message of justification by faith is the third angel's message, and I have answered, 'It is the third angel's message in verity.'"-Review and Herald, April 1, 1890.
Justification by faith, it is affirmed, is "the third angel's message in verity."
That means that the message of justification by faith and the third angel's message are the same in purpose, in scope, and in results." A.G. Daniells
VERITY: a true principle or belief, especially one of fundamental importance.
