It is quite interesting that they have those almost-masonic rituals in the LDS-temples.
Not sure how this relates to the posted article , but the Masonic rituals and LDS endowment only have a few outward similarities, particularly since the LDS endowment changes a number of years ago. Note also, that not all Masonic ritual is the same.
Further, the LDS ceremony and the Masonic ritual are staged in different era and involve different themes. One is a creation story involving covenants with God. The other occurs at the building of King Solomon’s Temple and involves promises made with other men.
Edit: I see that you are not yet a Mason, and so it seems odd you would speak of s knowledge of Masonic ritual.
