Not quite. The purpose of Jewish temple ceremonies was to offer sacrifice to God. The purpose of Mormon temple ceremonies is to swear oaths of allegiance to the LDS church, and to learn the “signs and symbols” needed for entrance into heaven. The allegience is in a vow of consecration, not to Christ but to the “building up of the Kingdom of God” (read: building up of the LDS church). (“You and each of you covenant and promise before God, angels, and these witnesses at this altar, that you do accept the Law of Consecration as contained in the Doctrine and Covenants, in that you do consecrate yourselves, your time, talents, and everything with which the Lord has blessed you, or with which he may bless you, to the Church of Jesus Christ of Latter-day Saints, for the building up of the Kingdom of God on the earth and for the establishment of Zion.”)
It’s not the blessings a person gets in the temple that gets one into heaven, it’s those all important handshakes and code phrases that one learns that gives us the “tokens” to slip through the veil and into heaven. Without these handshakes and code words, a person cannot get into heaven. Of course, with a quick Google search, anyone can find the entire verbiage of the ceremony, and learn the phrases. There’s even a
video from Big Love with the end part of the ceremony, where the woman gets pulled through the veil, with language that is actually used in the temple. But Joseph Smith apparently did not prophesy about the Internet when he wrote the ceremonies and made people vow to keep them secret.
