Kevin DeYoung writes a very short but informative piece on Mormonism.  One thing that caught my attention was this statement:

"Mormonism continues to grow because of it missionary impulse and its COMMITMENT to doctrinal and ethical DISTINCTIVES." 

What’s sad I talked with a missionary to the Mormons some years ago and he said that they (Mormons) spend a a lot of time reaching into the Baptist arena because…we are not strong in our our knowledge of or commitment to BIBLICAL DOCTRINE.
