I was in the temple recently.  Following baptisms for the dead, I was getting ready to help confirm.  In my mind I was trying to review the words to confirm someone.  When I got in the room, I read the words and was surprised “by the power of the Melchizedek Priesthood” was not there.  In 2014, I noted that in the initiatory, the ordinance is simply performed “by authority.”  When we perform blessings, ordinations, setting apart, etc. for the living, we always use the words “by the power of the Melchizedek Priesthood,” but these words are absent from temple ceremonies.  (I can’t think of a single instance in which we invoke “Melchizedek Priesthood” during a temple ceremony, but rather it is “by authority” or perhaps “having been commissioned of Jesus Christ” in the case of baptism.)  Why do you think that is the case?  Are temple ordinances done by the Melchizedek Priesthood, or some other authority, priesthood or not?  Is it because women can perform some of these ordinances that we leave out the word “Melchizedek”?
