==Question: Why do Mormons use the Aaronic Priesthood, since Hebrews 7 states that the Aaronic/Levitical Priesthood was "changed" to the unique priesthood "after the order of Melchizedek" held by Jesus Christ?==
===The idea that the Melchizedek Priesthood superseded the Aaronic Priesthood is a correct one, but this does not necessarily imply that there is no Aaronic Priesthood===

As other Christians see it, the Aaronic Priesthood is like a small glass of water that is replaced by a fruit juice (the Melchizedek Priesthood).  They are distinguished from each other, in most Christians' eyes, as quite separate things.

The LDS would use a different metaphor to explain things: they might compare the Aaronic Priesthood to a glass of water that is filled only part way.  Instead of being replaced by an entirely different drink, more water is poured into it until it is a full glass (the Melchizedek Priesthood).

===From a Mormon perspective, the two priesthoods are really the same substance: the power of God delegated to man===

From whence do the two priesthoods originate?  The same source&mdash;God.  What is the purpose of the two priesthoods?  They bring mortals to the Lord (note that only the Melchizedek Priesthood can do so entirely&mdash;see [http://scriptures.lds.org/en/heb/7/11#11 Hebrews 7:11]&mdash;but the Aaronic Priesthood was instrumental in keeping ancient Israel holy and pure).  The Aaronic Priesthood is merely a limited form of the Melchizedek Priesthood, or (as LDS scriptures call it) an "appendage" to it ([http://scriptures.lds.org/en/dc/107/13-14#13 D&C 107:13&ndash;14]).

Elder M. Russell Ballard of the Quorum of the Twelve Apostles illustrated the doctrine clearly:

<blockquote>
Since all priesthood is Melchizedek, the Aaronic Priesthood being a portion of it, one does not lose the Aaronic Priesthood when he is ordained to the Melchizedek Priesthood [...]<ref>M. Russell Ballard, cited in ''Priesthood'' (Salt Lake City: Deseret Book Company, 1981), 72.</ref>
</blockquote>

===Why does the Aaronic Priesthood persist in the Church?===

So, if the Church possesses the Melchizedek priesthood, then why would the Aaronic Priesthood persist today?  The Aaronic priesthood serves as a 'preparatory priesthood' (see [http://scriptures.lds.org/en/dc/84/26#26 D&C 84:26].)  Just as the Levitical authority in ancient Israel acted as a "schoolmaster" to prepare Israel to receive Christ (see [http://scriptures.lds.org/en/gal/3/24-25#24 Galatians 3:24&ndash;25]), in the modern Church the Aaronic priesthood serves to school young men for service in God's kingdom on earth.

The modern Aaronic priesthood's organizational structure follows the pattern established by the New Testament Church, and consists of Deacons (see [http://scriptures.lds.org/en/philip/1/1#1 Philippians 1:1], [http://scriptures.lds.org/en/1_tim/3/8,10,12-13#8 1 Timothy 3:8,10,12&ndash;13]), Teachers ([http://scriptures.lds.org/en/acts/13/1#1 Acts 13:1],[http://scriptures.lds.org/en/1_cor/12/28-29#28 1 Corinthians 12:28&ndash;29]), and Priests (see [http://scriptures.lds.org/en/acts/6/7#7 Acts 6:7]), and countless references in the Old Testament to Levitical/Aaronic 'priests'). 

Each Aaronic priesthood office is trusted with more responsibility, providing LDS young men with the opportunity to progress and mature until they are ready to receive the priesthood in full&mdash;the Melchizedek Priesthood.

===Aaronic priesthood duties and function similar to ancient Israel===

Despite some modern differences from ancient Israel, the Aaronic Priesthood is not much different compared to ancient times.

The Aaronic priesthood performs two ordinances (some Christian groups would call these 'sacraments').
#Baptism: John the Baptist held the Aaronic Priesthood, which holds the keys of baptism, and baptism is of course a fundamental part of salvation through Christ (see [http://scriptures.lds.org/en/acts/2/38#38 Acts 2:38)].  
#Sacrifice:  The modern Church does not, of course, sacrifice animals because Jesus Christ sacrificed Himself for us, giving us the last great sacrifice (see [http://scriptures.lds.org/en/eph/5/2#2 Ephesians 5:2)].  Yet, the Church rejoices in and recalls His sacrifice for us by partaking of the sacrament ("communion" or "the Lord's supper" in other denominations) [http://scriptures.lds.org/en/matt/26/26-29#26 Matthew 26:26-29)].  Thus, the modern priest repeats a ceremony of atonement and sacrifice through the sacrament of the Lord's supper; this plays a similar theological role to the animal sacrifices offered by Aaronic priests anticipation of Christ's atonement and resurrection.

===Separation of priesthood duties in the New Testament Church===

It should be noted that all priesthood was not equivalent in the New Testament Church either.  For example, many members had been baptized with water (an ordinance of the Aaronic priesthood) but had not yet received the Holy Ghost until one of the apostles laid hands upon them (a Melchizedek priesthood function).  (See [http://scriptures.lds.org/en/acts/8/15-19#15 Acts 8:15&ndash;19], [http://scriptures.lds.org/en/acts/19/2-6#2 Acts 19:2&ndash;6]).
