The Athanasian Creed begins the last portion with these powerful words:
Furthermore, it is necessary to everlasting salvation that he also believe faithfully the incarnation of our Lord Jesus Christ.
The creed continues with an in depth explanation, very carefully bringing forth the reason for the incarnation and the importance of what the Scriptures teach. Yet the authors of the creed were also very careful not to say more than what the Scriptures declare, without speculating on those things that the Scriptures leave undeclared. It truly is a marvelous creed.
The texts for the Nativity of our Lord, Christmas Day, are wonderfully explained by this creed, and thus it is utilized as part of the sermon this year. The sermon, “In the Majesty of the Name of the Lord His God,” is available in text and audio here.
