What would I need?

You should start with 3 things
1. Mormon Garments
2. LDS Quad. (mormon scriptures)
3. counselling to make sure you don't lose perspective while you are in the inside. :)

1. (white) Trench Coat, belt ties hanging.

2. pair of those 'Groucho glasses' with no lens, bushy eyebrows.

3.Humphrey Bogart persona; practice by saying:
"Play it Sam; Play 'As Time Goes By'"

4. Appropriate electronic support: pin-hole video cam, lapel mic; notebook, vehicle with Bogus plates.

5. Reasonable cover: Molly Mo, Mo Kids, house, career, & other accrutrements.

I forgot, I don't know your background but you don't need to know sh1t about the church as they don't care. Just look and act like one and you are in.

Hahaha I've been thinking about doing the same thing...showing up just to collect all the creepy info I can...maybe get some video footage...it'd be good for a laugh

A very bad idea for you! Stay away.

Call LDS missionaries. They will tell you all you need to know to fit in.

My question is "Why?" You know that nothing interesting happens there, right?

The real trick is "infiltrate the temple", which is where the wierd/creep stuff is.

That would require at least a year of posing as a TBM convert.

Nope. It only requires a small piece of easily forgable paper behind protective plastic.

If you want to go badly enough, this wouldn't prove a challenge.

I know this used to be true. However I was told (so it must be true) that the barcode was to prevent forgeries. When I went the always scanned my card and my info would show up on the screen.

DH and I went to a ward for three months before we told them we weren't members.

LOL, why the hell did you do that? :)

you could pretend to be an investigator. Then you could see if they make you attend different classes from the others. Make note of any "love-bombing." Ask regular members about their personal beliefs. But you can easily get more accurate information here at RfM.

You don't need anything, just show up. But, my recommendation is don't bother, you'll just be bored. There's nothing interesting going on and no interesting conversations to be had. Check out the youtube video already posted of a Sacrament meeting and you'll see that you aren't missing out on anything.

That video should be compulsory viewing for any online investigator.

I've thought about it but I'm afraid someone will ask if I'm a member or not (don't they always?) and then I have to hem and haw and I don't want to be branded an investigator.

Don B: as far as I know, part of the 'APPEAL' of mormonism is being a "uniform" (unitary) system of beliefs. doctrine, and practice; Mormons are discouraged (understatement) from expressing any deviating individual beliefs;
I think asking anyone their 'individual' beliefs is offensive.

Anyway, most mormons Parrot what they've been spoon-fed, it's their 'Best' plan!

'Individual Beliefs' are anathema to mormonism; how could it achieve 'Correlation' with individual beliefs????

Dead eyes
Sing Songy voice
Frumpy wardrobe (in a poor ward)
Fake boobs (in a rich ward)

To OP:

WHY do you want to "infiltrate"? How deeply do you want to "infiltrate"? What do you actually mean by "infiltrate"?

Forget branches, wards, or even temples. The really worthy target of infiltration would be either the Church Office building or the records storage area the church has in that hollowed out mountain. Honestly, other then the military or a James Bond villain, who has a giant underground facility within a hollowed out mountain?

When they ask you to stand and introduce yourself, say you are in town temporarily as part of your job and that you are from some distant state. Otherwise they will send to Salt Lake City for your membership records.
