In addition to sermons on scripture, sermons on confessions are common. It would be very useful to be able to search for sermons on specific articles on a confession. Yes, I realize that in some case this would require that you add a datatype, but that datatype is necessary for other reasons as well.
Example of such sermons:
- Nakskow, Petrus Sachariæ. The Articles of Faith, of the Holy Evangelical Church, according to the Word of God, and the Ausburg Confession. Translated by Jochum Melchior Magens. New York; Philadelphia: J. Parker; W. Weyman; Godfried Muller; Schleydorn, 1754.
