Hebrew feminine noun, refers to our connection with God, and the power of God used by mankind. In the Latter Day Saint movement, the Priesthood is a term used for three distinct things:
1. the power of God
2. service to others
3. the ministry (including Offices of the Priesthood).
When we pray and that prayer is answered, that is the priesthood in action.
Some things we do, as seekers, disciples, and ministers require us to hold an Office of the Priesthood to run parts of the various sects and other organizations. There are two ways we may use God’s power. The first is theurgy. Theurgy is when we attempt to better ourselves through God. The second way we use God’s power is thaumaturgy. Thaumaturgy is also known as “wonder working” or “miracle working.” These would be the gifts of the Spirit.
All gifts of the spirit use the priesthood and may be used by men and women alike. All miracles may be considered thaumaturgy, and some require the priesthood keys. Yet miracles may also be performed by men or women that are not ordained to the ministry, based on their faith and the grace of God. God has no limits, thus neither does the priesthood.
