Innumerable ages having passed since the creation of the world, when in the beginning God created Heaven and earth and formed man in his own image;
many more centuries after the flood, when the Most High placed his rainbow in the heavens as a sign of the covenant and of peace;
from the migration of Abraham, our father in faith, from Ur of the Chaldeans, twenty- one centuries;
from the exodus of the people of Israel out of Egypt, led by Moses, thirteen centuries;
from the anointing of David as King, about one thousand years;
in the sixty-fifth week according to Daniel’s prophecy;
in the year of the one hundred and ninety-fourth Olympiad; from the founding of the city of Rome,
seven hundred and fifty-two years; in the rule of Caesar Octavian Augustus, the forty- second year;
the whole world being at peace: Jesus Christ, eternal God, the eternal Father’s Son, being pleased by His coming to consecrate the world, by the Holy Spirit conceived, nine months having passed since His conception, in Bethlehem of Judah was born of the Virgin Mary, and became man. [KNEEL]
