Christ and Red, Red, Wine
At the very top of this window is the mother pelican in the seeming act of feeding her young. Very early in the second century, the pelican became a symbol of Christ. In so far as I can put together the ancient sailors believed that the pelican opened its own breast and fed its young with its own blood. This identifies it easily with Jesus who shed His blood for you and me, that we might have life. Given the pink colored tinge of the inner beak of the pelican and coupled with the blood from regurgitated fish. I can see how they thought it opened its own breast to feed its young and hence the link to Christ who said, “Unless you drink mu blood ye cannot have life in you.”
Did you know that in Jewish circles if a man offered a cup of wine to a woman, it was a proposal of Marriage? If she accepted, the marriage was to be. Every Sunday you are offered the cup of the new marriage consummated when Christ entered once for all into the heart of God. Soon, God willing, we will all join Him.
Sincerely yours in Jesus through Mary,
Become like Jesus
Live for the Triune God
Seek the Light of Our Lord Jesus Christ
See you on the High Ground!
