What does deacon mean?
A deacon is an office-holder in Christian churches whose role centers on service, assistance, and charity. In Catholic, Eastern Orthodox, and Anglican traditions, the deacon is an ordained member of the clergy ranking below the priest, authorized to assist at worship, proclaim the Gospel, baptize, and perform other designated duties. In many Protestant bodies, particularly Baptist churches, deacons are instead lay officers chosen by the congregation to support the pastor and manage practical church affairs. The term derives from the Greek diakonos, meaning 'servant' or 'messenger,' reflecting the position's original emphasis on humble service rather than authority. Related forms include deaconess (historically a woman in such an office) and diaconate (the office or order itself). Because its exact status differs across denominations, the word's connotations range from ordained clerical dignity to trusted lay leadership.
An ordained cleric in certain Christian churches ranking below a priest, responsible for assisting in liturgy and charitable service; also, in some Protestant denominations, a lay officer who assists in governing the local church.

The word 'deacon' comes straight from the Greek for 'servant' — making it one of the few English titles whose literal meaning is simply 'the one who serves.'

Etymology of deacon
The word 'deacon' entered Old English from Latin diaconus, which was borrowed from Greek diakonos, meaning 'servant,' 'attendant,' or 'messenger.' It was adopted very early by Christians to denote an office of service in the church, described in the New Testament, and has been in continuous religious use in English since before the Norman Conquest. The same Greek root underlies the related terms 'diaconate' and 'deaconess.'

How deacon is actually used
The word carries a formal, ecclesiastical register. Its precise meaning varies significantly by denomination: in Catholic and Orthodox usage a deacon is an ordained member of the clergy one step below priesthood (with 'permanent deacon' distinguishing those not proceeding to ordination as priests), while in many Baptist and Congregationalist churches deacons are lay leaders rather than ordained clergy. Capitalization varies; it is usually lowercase unless part of a formal title.
