This Christmas night, peace was bestowed upon the whole world; so let no
one threaten.  This is the night of the Most Gentle One; let no one be
cruel.  This is the night of the Most Humble One; let no one be proud.
Now is the day of joy; let us not revenge.  Now is the day of goodwill;
let us not be mean.  In this day of peace let us not be conquered by
anger.  Today the Beautiful One impoverished Himself for our sake; so
you rich ones, invite the poor to your table.  Today we received a gift
for which we did not ask; so let us give alms to those who implore us
and beg.  This present day's fast opens the heavenly door to our
prayers.  Let us open our door to those who ask our forgiveness.  Now
the Divine Being took upon Himself the seal of humanity, in order for
humanity to be decorated by the seal of Divinity.

St. Isaac the Syrian, 7th century

Christ is born!  Glorify Him!
