Could you be more specific of these demonic temple ordinances?
Mormon Temple Endowment - 1931 Version
The above site gave a security error, but it has more of the information that you were seeking. Try not to yak if you decide to read the whole endowment. When I went to the temple in 1976, the endowment was similar to what this site presents, but was somewhat more subdued than the 1931 endowment cited. Excerpts from the 1931 endowment:
...
“ …
you will not forget that the utmost secrecy is to be observed with respect to these proceedings. They are not to be even spoken of to each other."
The left arm is here placed at the square, palm to the front, the right
hand and arm raised to the neck, holding the palm downwards and thumb
under the right ear.
Adam--"We, and each of us, covenant and promise that we will not reveal
any of the secrets of this, the first token of the Aaronic priesthood,
with its accompanying name, sign or penalty.
Should we do so, we agree
that our throats be cut from ear to ear and our tongues torn out by
their roots."
Adam--"All bow your heads and say Yes."
As the last words are spoken the right hand is drawn swiftly across the
throat and the hands dropped from the square to the sides.
...
“ … receive the Second Token of the Aaronic Priesthood."
"We and each of us do covenant and promise that we will not reveal
the secrets of this, the Second Token of the Aaronic Priesthood,
with its accompanying name, sign, grip or
penalty. Should we do so,
we agree to have our breasts cut open and our hearts and vitals torn
from our bodies and given to the birds of the air and the beasts of
the field."
"All bow your heads and say yes."
The Sign is made by placing the left arm on the square at the level of
the shoulder,
placing the right hand across the chest with the thumb
extended and then drawing it rapidly from left to right and dropping it
to the side.
‘’’
" ... receive the First Token of the Melchizedek Priesthood."
The Sign is made by bringing both hands to the square, palms to the
front.
Peter--"We and each of us do covenant and promise that we will not
reveal any of the secrets of this, the First Token of the Melchizedek
Priesthood, with its accompanying name, sign or
penalty. Should we do
so, we agree that our bodies be cut asunder in the midst and all our
bowels gush out."
Peter--"All bow your heads and say yes."
As the last words are spoken the hands are dropped till the thumbs are
in the center of the stomach and drawn swiftly across the stomach to the
hips, and then dropped to the sides.
…
While the endowment was slightly less graphic in 1976, all three penalties were acted out in a similar manner. All three signs,tokens, and penalties were borrowed from the first three levels of "blue lodge" freemasonry termed Entered Apprentice; Fellow Craft, and Master Mason almost exactly as they appear in
Duncan’s Monitor a manual of Freemasonry from the 1800s, which I found online.
Too much?
