Would a message from God pass these Catholic rules on revelation?

Herein contains what we might call the paradox of revelation. As its meaning makes clear, you can’t have a “revelation” that tells everyone what they already know. However, having established a religion on those revelations, the teachings revealed through them become non-negotiable, and the ecclesiastical authorities become the arbiters of their interpretation. And so that means no further revelation is admissible if it contradicts what is already believed. Revelation of radical new truths, if accepted as real, thus makes future revelation of radical new truths impossible. To put it another way, what was absolutely valid for the establishing of a religion becomes by necessity invalid once it already exists.
