The term “worship” once had a broader meaning. I think in England they may refer to judges as Your Worship. In the U S court petitions use language such as We pray the Court to grant …
The older meaning might use “worship” in that larger sense, to attribute worth to.
Thus, we attribute “worth” to angels and saints. We attribute higher worth to Mary, and the fullness of worth - divinity - to God Alone.
It might seem more devout to restrict our language to God alone. But I think the current trend to reduce the importance of Mary and saints, and abolish angels all together, reflects a mentality that God is only a little more important than Me. There’s no room for intermediaries or intercessors.
Catholics, and Protestants, attribute “worth” to the flag for instance. Relics can be considered in the same category. When was the Imprimatur issued? Was the book originally written in English, or is this a translation?
