urious treatise on organ-building.
But it was not until the Fifteenth Century that the organ began to
be anything like the noble instrument which it now is, the most
comprehensive and important of all wind instruments.

Orientation.--The name given to the act of turning to the east or
Altar as an act of faith and worship in the Church service. (See
EAST, TURNING TO.) It is also an architectural term used in
reference to church buildings running east and west.

Ornaments.--By "ornaments" is meant the necessary furniture of the
church for the proper conduct of divine service, and the vestments
to be worn by the clergy. In this the Church of the present day is
largely guided by what is called the "Ornaments {204} Rubric" of the
English Prayer-book. According to this it would seem that among
the necessary ornaments for the proper furnishing of the church
are the following: the Altar, with its cross, candlesticks and
coverings; Paten and Chalice; Cruets, Font and Pulpit; and that
the necessary vestments of the Priest are the chasuble, alb and
girdle, stole, surplice, cope; for the Bishop the same with the
addition of the rochette, mitre and Pastoral staff.

Orphrey.--A band of embroidery used to ornament the vestments.

Orthodox.--In accordance with the doctrine of the Church; holding
fast "the Faith once delivered to the Saints." The Faith has been
defined by the Ecumenical Councils as set forth in the Creeds which
"ought thoroughly to be received and believed, for they may be
proved by most certain warrants of Holy Scripture" (VIII Article of
Religion).

P

Pall.--A square card, the upper side of which is covered with silk
the color of the Church Season and underneath with linen, loosely
stitched so as to be readily removed in order to be washed. It is
used to cover the Chalice when the Holy Eucharist is celebrated.

Palm Sunday.--The Sixth Sunday in Lent, the first day in Holy Week.
It commemorates the entry of our Lord into Jerusalem when the people
strewed {205} the way with palm branches and cried, "Hosanna to the
Son of David." It was formerly customary for worshippers to appear on
this day in procession carrying in their hands palms, or yew or
willow branches, which were blessed before the beginning of the
Communion Service. On Palm Sunday the Church has always begun to
set before God and man the Gospel account of the Passion of our
Lord, that by St. Matthew being read on this day. (See LENT,
