“The virtual eclipse of the 1888 message for decades has been the one factor almost entirely responsible for this erosion of basic Seventh-day Adventist confidence in the sanctuary doctrine and 1844. In 1889 Ellen white foresaw that opposition to the Jones- Wagner message was ‘to cause apostasy’ (CWE 31). An interesting phenomenon is apparent: those who fail to see Biblical support for 1844 likewise fail to appreciate the 1888 message; and the reverse seems operative as well. The 1888 message brought the sanctuary doctrine into clear focus and restored ‘its presiding power [in] the hearts of believers’ (EV 225); and the loss of that message tended to ‘remove its presiding power from the hearts of believers.’”
