ArchdeaconAn archdeacon is a senior clergy position in the Church of the East, Chaldean Catholic Church, Syriac Orthodox Church, Anglican Communion, St Thomas Christians, Eastern Orthodox churches and some other Christian denominations, above that of most clergy and below a bishop. In the High Middle Ages it was the most senior diocesan position below a bishop in the Catholic Church. An archdeacon is often responsible for administration within an archdeaconry, which is the principal subdivision of the diocese.
Diocesan bishopA diocesan bishop, within various Christian traditions, is a bishop or archbishop in pastoral charge of a diocese or archdiocese. In relation to other bishops, a diocesan bishop may be a suffragan, a metropolitan (if an archbishop) or a primate. They may also hold various other positions such as being a cardinal or patriarch.
Catholic missionsMissionary work of the Catholic Church has often been undertaken outside the geographically defined parishes and dioceses by religious orders who have people and material resources to spare, and some of which specialized in missions. Eventually, parishes and dioceses would be organized worldwide, often after an intermediate phase as an apostolic prefecture or apostolic vicariate. Catholic mission has predominantly been carried out by the Latin Church in practice.
Celtic ChristianityCeltic Christianity (Kristoneth; Cristnogaeth; Crìosdaidheachd; Credjue Creestee/Creestiaght; Críostaíocht/Críostúlacht; Kristeniezh; Cristianismo celta) is a form of Christianity that was common, or held to be common, across the Celtic-speaking world during the Early Middle Ages. Some writers have described a distinct Celtic Church uniting the Celtic peoples and distinguishing them from adherents of the Roman Church, while others classify Celtic Christianity as a set of distinctive practices occurring in those areas.
