Gethsemane Evangelical Lutheran Church. Lakewood. Choir Window. 1949?Representational Protestant and Catholic stain glass are often different. I find something new in some Protestant churches. Different denominations will put their particular history's leaders and heroes on glass, so Francis Asbury might appear in a Methodist church, and not much elsewhere. People would ask who is he? Most of the Old Testament is recognised by Protestants, and Old Testament personages are more often represented in Protestant churches than in Catholic ones. Sometimes, the person is obscure. There are a lot of names in the Old Testament, and some are not familiar to 99+% of people. Some names sound like Old Testament names, even if they are not familiar.
Catholic churches often have a St. Cecilia window, or painting in the choir loft. King David is sometimes found, angels more often. The window, supra, is entitled "O come let us sing unto the Lord". There is David with crown and harp, king and psalmist—familiar. Choir director, Chenaniah? The picture tells the story. Of all the passages in the Bible, who remembers this one?
And Chenaniah, chief of the Levites, was for song: he instructed about the song, because he was skilful. — 1 Chronicles xv. 22. KJV
And Chonenias chief of the Levites, presided over the prophecy, to give out the tunes: for he was very skillful. — 1 Chronicles xv. 22. Douay-Rheims 1899 America
