Really? Like the Oneness Pentecostal disbelief in the Trinity -- or how about the Seventh Day Adventist belief that Satan is jesus' brother
Nope, utter divisions in core doctrine
Talk about obfuscating things; cults are not part of the evangelical movement (and in fact they typically operate more according to Rome), and instead, as a result of a common affirmation of basic core truths then evangelicals (S. Baptists, etc,) have historically contended for these against those who deny such things as the Trinity (WTS), eternal torment (SDA), the eternal nature of God (LDS), and revisionist liberal views of Scripture, such as seen in the American Catholic Bible, as well as unScriptural traditions of men..
Modern evangelicalism itself as a distinct movement began as a reaction against against liberalism and became the primary contenders against cults and cultic groups.
In fact, if they had not historically contended for such evangelical truths and shown much fruits of regeneration then Rome, which largely preaches herself, would not have found them so much of a threat, in contrast to liberal Protestant denoms, whose overall fruit is more like theirs. Yet overall all churches which are included under the “Christian” umbrella are in spiritual decline.
