Naturally. I'm a little curious, though ... In your particular church, how would you and a hypothetical fellow member of that church who believes as I do resolve your hypothetcial dispute?
Likewise flawed is your claim that non-Nicene subscribers believe your second statement "Jesus is a creature (not consubstantial with the Father)".
Cool your jets, brother. I did not and do not make that claim.
"Jesus (is|is not) of the same divine substance as the Father" is the dispute addressed by the Council of Nicea. That's an historical fact. Also an historical fact is that the Council resolved the dispute in favor of the proposition: "Jesus is of the same divine substance as the Father".
Now, as to modern groups which don't like the Nicene Creed (or creeds in general), I have said nothing. I don't know how they resolve disputes, nor do I know how they codify their beliefs. That's their problem, not mine. If they wish to explain it, that's wonderful.
As I've opined elsewhere, the various creeds and confessions of the historic church have been a useful means of codifying and focusing key Biblical doctrines, and by extension are very useful in matters of church membership (covenants) or forming definitions of heresy for Protestants. Many "Protestant" churches, especially evangelical and non-denominational ones, reject all historic creeds as binding on themselves re matters of discipline or doctrine, and thus there is no simple way of determining whether they are "in the fold" (i.e. orthodox) or not.
By refusing to profess/acknowledge a creed, or at least publish an "articles of faith" / "doctrinal statement", these anti-creedal churches and believers functionally accomplish five things:
