Reading the Sermon on the Mount and the Sermon at the Temple side by side is interesting. A couple of observations from the first room of the ordinance.
1. In both Sermons, Christ notes that entry into or greatness in the "kingdom of heaven" (which is clearly the temple) depends on keeping the commandments accepted in connection with entry into the temple (see: Matthew and 3 Nephi). In Matthew, he then pretty clearly states that the religious establishment of Palestine of his day do not participate in the Worship of the Shalems.
2. Christ is in some sense the same as the altar.
