Some explanation. Mormon's believe that you need to know secret handshakes to get into heaven.
They learn these handshakes during a meeting in the temple called the endowment. Here is what they say about the endowment during the ceremony itself:
"Your Endowment is, to receive all those ordinances in the House of the Lord, which are necessary for you, to enable you to walk back to the presence of the Father, passing the angels who stand as sentinels, being enabled to give them the keywords, the signs and the tokens, pertaining to the Holy Priesthood, and gain your eternal exaltation."
These "signs and tokens" are the secret handshakes and their accompanying names.
The words the Google Home is saying in this video are the name of the last "token". So technically, it probably won't make it into Mormon heaven since it still doesn't know the secret handshakes, but it's a good start!
"Health in the navel, marrow in the bones, strength in the loins and in the sinews, power in the Priesthood be upon me, and upon my posterity through all generations of time, and throughout all eternity."
