To call Mary the Ark is not to exalt her above Christ. It is to recognize that the Incarnation did not happen in abstraction. It happened in her. And in her flesh, the Word did not merely dwell.

It was a declaration of theological fact.    Sources: https://www.catholic365.com/article/51313/why-mary-is-the-ark-of-the-new-covenant.html
