Main Difference
The main difference between Deacon and Priest is that the Deacon is a ministry in the Christian Church and Priest is a person authorized to lead the sacred rituals of a religion (for a minister use Q1423891)
Deacon
A deacon is a member of the diaconate, an office in Christian churches that is generally associated with service of some kind, but which varies among theological and denominational traditions. Major Christian churches, such as the Catholic Church, the Oriental Orthodox Churches, the Eastern Orthodox Church and the Anglican church, view the diaconate as part of the clerical state.
The title is also used for the president, chairperson, or head of a trades guild in Scotland; and likewise to two officers of a Masonic lodge.
Priest
A priest or priestess (feminine) is a religious leader authorized to perform the sacred rituals of a religion, especially as a mediatory agent between humans and one or more deities. They also have the authority or power to administer religious rites; in particular, rites of sacrifice to, and propitiation of, a deity or deities. Their office or position is the priesthood, a term which also may apply to such persons collectively.
