Some people cringe when they see the word "Xmas". But there is really no reason. The early Christians were mainly Greek speaking. When they were persecuted, they would abbreviate some correspondence. So, they used their letter P to represent Jesus and X to represent Christ. Even now you see some vestments or religious art that superimposes the X over the P to stand for Jesus Christ. Some non-Catholic preachers with little sense of Christian history have distorted our background. Whichever way you spell it, give glory to God.
