What is the formal name of the Mandalorian creed phrase often shortened to “This is the Way”?

The story behind the answer

The formal title in canon is the traditional creed that followers—especially the Children of the Watch—invoke when saying “This is the Way.” The distractors aren’t used in official sources: “The Creed of the Mandalorians” and “The Mandalorian Code” are generic-sounding labels, while “The Path of the Mandalore” is not a recognized term in dialogue or reference material.

In-universe, the creed traces back to Mandalore’s warrior culture and leaders like Mandalore the Great, guiding conduct on honor, loyalty, foundlings, and strict practices such as never removing one’s helmet (for certain sects). Characters like Din Djarin and the Armorer use the phrase as a communal affirmation, signaling adherence to tradition and shared identity across a scattered people.
