Slowcowboy asked in the last thread about how Mormons are like Catholics. The question can best be answered from a 20,000-foot view of the goals of Protestants, Catholics, and Mormons within Christendom.
The Catholic goals are (1) to protect and preserve the proclamation of the New Testament and (2) maintain the power and influence of the Catholic church as holders of the keys of the priesthood. Protestants had two primary political goals, (1) rationally clarify and re-proclaim the message of the New Testament as the basis of the church and (2) break the political power of the Catholic church. The Mormons goals are (1) reinstate spirituality over rational theology as the primary mover of the church, (2) re-institute the earthly priesthood authority instituted at the time of Christ, (3) establish Zion in preparation for the second coming. All things considered, the Mormon goals are not unreasonable in the context of the history of Christendom. However, I think the Mormons are operating with some distinct disadvantages in their understanding of Christ.
