Both George Eliot and John Henry Newman understood character more or less on the Aristotelian model, as the all-important key to both thought and action. Poor character leads to poor reasoning and a limited range of action; good character allows for the reverse. This means that both place a tremendous emphasis on the right kind of community and tradition, for these in all their interrelation make up the medium within which character is formed. Moreover, neither understands community or tradition as static, presuming rather that the two develop through history.
The difference: Eliot does not see a telos in history; Newman does. While she flirts with the secular, rationalist eschatology of the Comteans, Eliot is not in the end convinced that we're inevitably moving forward. Certainly the theology-to-metaphysics-to-positivism progression is the path which individuals follow toward enlightenment, but Eliot is too naturalistic to accept a rosy view of some future state of universal, millenial positivism. So she takes a view more like Darwin: we're evolving, and doing our best at it, but that doesn't mean we're getting anywhere objectively better than where we've been before. While Newman might accept some form of this vision as true for the unbeliever, he understands Christian history as directed toward fuller and fuller understanding of our faith in Christ: a clearer and clearer image of the Person we've already grasped through faith. For Eliot, history is change, and to know this is is to know the truth; we have to find a way to be happy and peaceful in such a world, caring for one another in spite of the fact that there's no ultimate point to it. Newman, of course, sees Christ as the key to history, and participation in him (and through him, the Trinity) as its end, so that the goal is to make our way toward and into him at all costs.
The consequence: Eliot thinks that a community-based, traditional Christian faith is damaging, breeding personal characters that rely upon falsehoods, characters which will put them in conflict with one another, leading away from sympathy, peace, and happiness; Newman, on the other hand, supports such a faith as breeding characters that rely on both natural and supernatural truth, allowing persons to reach their end in Christ. For Eliot, then, the few who know best (i.e. those who have really achieved rational distance from their traditions) ought to remake the myths--the communal traditions--that so define the lives of the ignorant masses. They'll have to do this, moreover, in every generation, as human nature is in a state of flux, so that our myths will require regular adjustment. All this must be done, out of sympathy for the peasants (and we're almost all of us peasants). For Newman, however, we've already got a true myth in which to live--the communal tradition of the Church--and we had better bring as many into it as possible, for their own sakes.
An interesting point in all this: both Eliot and Newman strain against the usual individualism of modern liberal thought, instead viewing character (and therefore thought and action) as necessarily, integrally related to habit, community, and tradition. Still, Eliot has in the end to imagine at least her few illuminati as radical individuals, abstracted from the mythology of their lives, for otherwise, who would be rationally fit to weave the ever-evolving myths for all the rest? Newman, on the other hand, avoids the insufficiencies of the liberal anthropology altogether, by imagining even the most brilliant (e.g. himself) to be inseparable from the traditions that give them life, and for the faithful, life abundantly. He thus successfully promotes a postliberal view of character in its relation to historical life.
