Miaphysitism is the christology of the Oriental Orthodox Churches. These Churches believe that Christ, the Incarnate Logos, is of two natures "human" and "divine" that are united in one hypostasis "without mingling, without confusion, and without alteration". These two natures "did not separate for a moment or the twinkling of an eye".
From the soteriological viewpoint, if only an ordinary man without a trace of sin (and not the Incarnate Logos) died on the cross, then this would not be enough as an atonement for the (infinite) sin of mankind in all ages against the infinite God (the soteriological necessity).
