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).
