Zenit’s Fr McNamara addresses Liam’s favorite point on the Sanctus. When I composed my Olive Leaf Mass a few years back, I used Liam’s suggestion and composed one line for “Holy Holy Holy,” and another for “Lord God of power and might.” This is one Mass setting I may not refinish for the new Roman Missal, however.
By the way, the shape note tune I used was called “Patton.” I didn’t think the Patton Mass was a good title. “Patton” came from a shape-note hymnal called The Olive Leaf. Hence a better title.
