Cathedral.--The word "cathedral," derived from the Greek word _cathedra_, meaning a seat, is the name given to the Church where the Bishop's seat or throne is. As such, it is the chief church in the Diocese and the centre of the Bishop's work. Around it are gathered the educational and charitable institutions of the Diocese. It is the centre of Diocesan activities and of the mission work carried on by the Cathedral clergy under the direction of the Bishop. Of the Cathedral as an institution a recent writer has said: "It must be granted that a Cathedral in its origin was nothing more than a missionary creation, where the Bishop of a partly unevangelized country placed his seat with his council of clergy grouped around him, whose duty was to go forth into the surrounding districts with the message of the Gospel, to plant smaller churches which should be subordinate or parochial centres, and to return again periodically to the Diocesan church as headquarters, for the counsel, direction and inspiration of their chief." (See DIOCESE). Catholic.--The word "Catholic" was very early adopted as descriptive of the Church founded by our Lord and His Apostles. It means universal, or embracing all. In this sense the Church is catholic in {49} these three things, (1) It is for all people; (2) It teaches all the Gospel, and (3) It endures throughout all ages. This distinguishes the Christian Church from the old Jewish Church which was but temporal, local, national. Again, the word Catholic is used as being descriptive of the orthodoxy of any particular Church or individual as being in agreement with the one, undivided Church which has expressed itself in the Ecumenical or General Councils. The word is, also, used to describe that which is believed on the Authority of the Church, as for example, the doctrine of the Blessed Trinity is a _catholic_ doctrine because it is the universally accepted teaching of the Church and having the sure warrant of Holy Scripture. Thus we learn that the word _catholic_ is a very significant term and sets forth the real nature of the Church and her teachings. It enables us to test our own orthodoxy, to know whether we are loyal and true, in accord with "the Faith once delivered to the Saints," and, without doubt, will save us from being "carried away with every blast of vain doctrine." This word, then, so greatly misunderstood, so wrongly used, yet meaning what it does, ought to be used with thoughtful care. For intelligent Churchmen the term "Catholic Church" should not mean, nor be used to mean, simply the Roman Church, but rather that glorious body in which we declare our belief when we say in the Creed, "I believe in the Holy Catholic Church." Celebrant.--He who celebrates the Holy Eucharist {50} whether Bishop or Priest, is so called. A deacon cannot celebrate or administer the Holy Communion. Ceremonies.--(See RITES AND CEREMONIES).
