Thanks, Shim.
Rumar,
I realized I was so passionate about the essence of what I believe is spirituality, that I didn't answer your question... & I still probably won't answer it completely. but I'll tell you what I was taught...
I grew up in The Church of Jesus Christ of Latter day Saints...(lds)
The main differences between the "lds" church & other Christian churches are...
1. Continual revelation - modern prophets, apostles & 70
2. In addition to the Bible - the Book of Mormon, Pearl of Great Price & D& C are also studied scripture
3. Heavenly Father, Jesus & Holy Ghost considered 3 distinct personages
4. Babies are born innocent - children are baptized upon "age of accountability" - 8 yrs.
5. Salvation based not only on faith but also works
6. Belief in pre & post life existence... progress after death - levels of heaven
7. Cross symbol isn't used - it's considered a sad reminder of the way a loved one died
8. Personal revelation & priesthood power available for all members (even women perform some priesthood ordinances in temple)
9. Temple buildings & ordinances based on ancient practices & Masonry
What else...
Members give A LOT - in money, time & energy... all jobs in the church are unpaid volunteer "callings" - by all of the members (except tip top presidencies), monthly visiting & home teaching (which I love), Family Home Evenings, Geneology & Temple Work, Word of Wisdom (no drinking alcohol or coffee), service - including humanitarian... (there's more but you get the idea)
There are also the bad marks in the church's past (but this could go for other groups also)...polygamy & denial of priesthood to blacks, lack of financial transparency, chauvinistic ways, & cult-like or clickish nature.
Although my beliefs have drastically changed from orthodox Mormonism, I still believe it to be a good organization - just not to be taken too literally. The lds way of high standards, service & love - is something to be admired.
