Seems rather strange to combine evangicals and mormons and leave out all others.
I think it's for political reasons and not "faith".
Typically "Evangelicals" are social conservatives like Mormons - as opposed to mainline Protestant churches (Episcopal, Presbeterian, etc) that are pretty-much sold out to the Liberal agenda.
And I guess Roman Catholics, although the Church is officially pro-life, pro-family, etc, many of the adherents are socially liberal (except Freepers, of course).
Evangelicals believe in the great commission Jesus gave us.
“All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
Mormons are not Christians. Catholics and Protestants believe in the Trinity. Mormons do not.
Mormons do not believe in the same god as Christians. Their Mormon book is totally different the the bible. They believe they will live on different planets and if good enough, get there own planet to run when they die.
