Ellet Joseph "E.J." Waggoner (January 12, 1855 – May 28, 1916) was a Seventh-day Adventist particularly known for his impact on the theology of the church, along with friend and associate Alonzo T. Jones at the 1888 Minneapolis General Conference Session. At the meeting of the General Conference of Seventh-day Adventists Ellet J. Waggoner along with Alonzo T. Jones presented a message on justification supported by Ellen G. White, but resisted by church leaders such as G. I. Butler and others. He supported theological issues such as the meaning of "righteousness by faith", the nature of the Godhead, the relationship between law and grace, and Justification and its relationship to Sanctification.
