to the one service
appointed by our Lord Himself. In the Primitive Church an ordinary
Christian would not have considered that he had kept the Lord's Day
as a day of worship if he had not attended a celebration of the
Holy Communion. When, therefore, our people grasp these Scriptural
ideas, then no longer can it be said that worship is a "Lost Art"
among the American people. (See HOLY COMMUNION; also RESPONSIVE
SERVICE.)

X

X.--The letter X resembles the shape of the Cross of St. Andrew,
which has come into quite prominent notice as being the badge of
the BROTHERHOOD OF ST. ANDREW (which see).

X P.--These letters belong under this head only in appearance as
they are in reality the first two letters of the Greek word
_Christos_, meaning "Christ." The X is the Greek letter _Chi_ and
is equivalent to the English letters "ch"; the P is called _Rho_
and is the same as the letter "r;" they thus represent the first
three letters of the word _Christ_. These two Greek letters are
used in Church decorations either separately or as a monogram, as
a symbol or emblem of our Lord. {282}

Y

Y Cross.--By reason of its shape, the Cross embroidered on the
CHASUBLE (which see) is called the Y Cross, and is intended to
represent the outstretched arms of our Blessed Lord on the Cross,
and symbolizes the Sacrifice which He there offered for the sins
of the whole world, of which the Holy Eucharist is the perpetual
Memorial.

Year.--(See CHRISTIAN YEAR.)

Yule.--The old English name for CHRISTMAS (which see). A word of
doubtful origin.

Yule Tide.--The season or time of Christmas.

Z

Zealot.--One of a fanatical Jewish sect, which prevailed in the
time of our Lord. In the New Testament, this name is given to one
of our Lord's Apostles, namely, ST. SIMON (which see).

Zuchetto.--The name give to a skull cap worn by the clergy instead
of the biretta; when worn by a Priest the color is black, but that
worn by a Bishop is purple. {283}
