How so? If it's outside of the Chantry...and if several races can lead and join it, it isn't a religious war lead by the Chantry. Otherwise, we'd all be forced to be apart of the Chantry doing everything in the name of the Maker. Which David Gaider and others have promised us isn't going to be the case.
If that's how you wish to interpret it, as a matter of religion, then have fun with it. To each their own.
Being beholden to the Chantry is a type of relationship- not being beholden to the Chantry doesn't mean a lack of relationship. You can be a part of the Chantry without being led by the Chantry and doing everything in the name of the maker. Or you could force the Chantry into a partnership with you, using its influence to support you rather than direct you. Gairder's promise is about a type of relationship, not a lack of any relationship at all.
It's pretty much the shitick of every Bioware protagonist in the last decade. You are an independent agent loosely or officially associated with group X, but are not forced to adopt their worldview or act in their name even if you share interests. Commander Shepard of the Spectres/Cerberus/Alliance, The Warden Grey Warden, Hawke the Champion of Kirkwall. None of these were characters beholden to their patron faction/identity.
Besides, what happened to that being your last words on the subject?
