Nonsense. You are now grasping, hoping that the following jab at non-sequitur will save you--it will not:
"
The Year of Our Lord" is an idomatic expression that helps precisely establish the date of the document; it does not make a statement of principle, it does not establish a foundation in Christ.
"Who" doesn't come into it; the Blessings that are secured, are Blessings that come from Liberty--exactly as it is written.
