Baptism into the LDS church is required for entrance into the Celestial Kingdom. People who were Evangelicals in mortality but who accepted their proxy baptism are no longer Evangelicals, they are LDS. Thus, by definition only LDS will be in the Celestial Kingdom, including many who were Evangelicals during their mortal life. The statement as given referred to Evangelicals being in the Celestial Kingdom, implying they had gotten to the Celestial Kingdom without baptism.
