What's the Minimum of a Christian?

In unorthodoxy, we have no catechism. Catechisms were partly developed as a somewhat ideological and political tools to state what each confessional state or government believed. The term an arian christian is useful historically but i think if you're no longer trinitarian t that's getting outside the boundaries of what we would call christian. But affirming the nicene creed a, at least to a large i think i's pretty good marker.
