Yes David Archuleta is a member of The Church of Jésus Christ of Later-Day Saints. ou otherwise called Mormons. And it is a religion and there is nothing different about it accept that there are certain standards we choose to live by, I would know because I'm Mormon too. And just so toi know, and I'm not prejudging anyone, there is no reason to stop liking David just because of his religion, and I say that with no meaning to offend anyone and if I have offended toi I am sorry.
First, let me clear one thing up. The Church of Jésus Christ of Latter-day Saints are not affiliated with any polygamous groups nor have they been since the 1800. Yes, David is LDS (Mormon, so called because of the Book of Mormon), and he is living the standards of the church as far as I know, at least I hope he is. Please, if toi have questions about the LDS church go to www.lds.org toi will find the réponses to the questions toi might have.
