Mormon Definitions, Christian Definitions
Atonement: Jesus suffering for our sins in the Garden of Gethsemane and then dying on the cross so that he could be resurrected to allow for all to have general salvation and for all to work for their individual salvation.
Jesus dying on the cross for our sins and rising from the grave on the third day to give us forgiveness and freedom if we have faith.
Aaronic Priesthood: The "lower" priesthood, sometimes also called the Levitical priesthood, usually given to boys upon turning 12 and including responsibilities such as blessing and passing the sacrament and, for the 16+ boys, baptizing.
A priesthood in the Bible established only for descendants of Aaron and which was for sacrifice in the Tabernacle or Temple. The men of the tribe of Levi would help the priests of Aaron in their duties and in minor sacrifices.
Baptism: An ordinance required for individual salvation, a literal washing away of sins.
An act of declaration to outwardly show the inner cleansing of the Spirit, not required for salvation but strongly suggested if the individual is able.
Bible: The Word of God only as far as it is translated correctly (Articles of Faith). Just one book of scripture on LDS canon.
The inspired and complete Word of God.
Celestial Kingdom: The highest of the three levels of heaven.
There is no Celestial Kingdom, only celestial beings, e.g. angels
Church: The LDS church as a denomination, including its whole structure and laws.
The body of believers in Christ.
Damnation: Eternal progression being stopped. E.g., after resurrection, one is cut short from continuing in their journey to godhood.
Being sent to hell.
Elohim: The name of God the Father.
The title or word for God in Hebrew.
Godhead: The three gods working together as three separate beings who are one in purpose; God the Father, Jesus, and the Holy Ghost.
The Trinity. One God, with three separate personages, or manifestations.
Gospel: The laws and ordinances of the LDS church.
The "good news" of Jesus Christ.
Jehovah: The person of Jesus Christ in the Old Testament.
The English version of the sacred name YHWH, or Yahweh, which is God's name, the great "I AM."
Jesus: The firstborn of God the Father, our spirit brother, and third person of the Godhead.
The Word made flesh, God among us
Marriage: An eternal institution necessary to reach the Celestial Kingdom.
A covenant between a man and a woman that doesn't continue after death because it is unnecessary.
Melchizedek Priesthood: The greater priesthood of the LDS church, held by adult men and including the responsibilities of performing of all higher ordinances.
A priesthood held only by Jesus, as he is our High Priest (there's only ever one) and he was not born of the tribe of Levi. Melchizedek was a "type" of Christ, or a shadow of what was to come.
Pre-existence: Our existence with God's as his literal spirit children before coming to earth to receive bodies and earn our salvation.
There was no pre-existence. We are created, and while he knows us before we exist, we do not exist until we are in our mother's wombs.
General salvation--through grace, all will be resurrected and then judged according to their deeds and placed into the appropriate level (or glory or kingdom) of heaven.
Individual salvation--through grace plus obedience (works), the individual can earn their level of heaven. Only acceptance of the Mormon Church as the only true church and reception of its ordinances will guarantee a place in the highest level of heaven.
"There is no salvation outside the Church of Jesus Christ of Latter Day Saints." (Doctrines of Salvation, 2:350)
Forgiveness of sins so that we can live with God, since He cannot abide sin in heaven due to His perfect nature. We obtain forgiveness through faith alone.
Satan: Spirit brother of Jesus, who rebelled against God's plan because he wanted the glory.
A fallen angel.
Are the definitions the same? Not at all. They use Christian/Biblical words, but they do not have Biblical meaning.
