Here's a few "Christians" who believed in some of those things. It's a long read but very interesting. You may be surpised what Justin Matryr, Origen, Tertullian, Barnabas, Hippolytus, Eusebius, Iraneus, Lactantius, Polycarp etc. believed.
Restoring the Ancient Church: Joseph Smith and Early Christianity
A Restoration Church
The Church of Jesus Christ of Latter-day Saints (Mormon) is a radical religion by the standards of most modern religions--and it was considered even more strange in the time and place it originated. Perhaps no other major religious movement in American history has given rise to so much controversy, curiosity, admiration, and animosity. The Church has been variously described as a non-Christian "revival of primitive paganism in a modified form"2, a "cult,"3 and, by a much more sympathetic observer, a completely new Christian religious tradition.4 But what does it claim for itself?
Mormonism emphatically claims to be Christian--but considers itself neither Protestant nor Catholic. Rather, it differs from both in that it claims to be the restored Church of Jesus Christ. That is, the Church claims that all other Christian traditions have come down to us as incomplete remnants of the original Church which Jesus organized, which necessitated God restoring the true body of Christ to the earth through a prophet--Joseph Smith, Jr. Thus, the Latter-day Saints claim their church is an actual restoration of primitive Christianity, as it existed under the Apostles in the first century A.D.

As for the Mormon/Evangelical split. As a Mormon I had preconcieved notions about Evangelicals and misunderstood many of their beliefs. This book helped me change some of my ignorance and helped me understand where Evangelicals were coming from in our differences.
How Wide the Divide?: A Mormon & an Evangelical in Conversation (Paperback) by Craig L. Blomberg (Author), Stephen E. Robinson (Author)
Book Description - Voted one of Christianity Today's 1998 Books of the Year! Mormons and evangelicals don't often get along very well, at least not once they begin to discuss their religious beliefs. They often set about trying to convert one another, considering the faith the other holds as defective in some critical way. Unfortunately, much of what they say about one another simply isn't true. False stereotypes abound on both sides, preventing genuine and helpful communication. Having discovered this sad state of affairs, Craig Blomberg, a committed evangelical scholar, and Stephen Robinson, a committed Mormon scholar, set out to listen to one another and to ferret out the real agreements and disagreements between them. In the conversation that develops, you will read what each believes about key theological issues--the nature and bounds of Scripture, the nature of God and deification, the person of Christ and the Trinity, and the essentials of salvation--and see how they interact with one another. What they agree on may surprise you. Though this book does not sweep differences under the rug, it is meant to help Mormons and evangelicals know and tell the truth about one another. It does not expect to end evangelistic efforts from either side. In fact, it may help to promote more effective communication because it can help to get rid of misrepresentations from both sides. In the end, however, you will be able to judge for yourself just how wide the divide between them is.
