But this is what leads the heretics Cf. Sever., Ep. 2 ad Joannem. astray, viz., that they look upon nature and subsistence as the same thing Anast. Sinaita, in ῾Οδηγῷ, ch. 9; Leontius, contr. Nest. et Eutych.. For when we speak of the nature of men as one Greg. Naz., Ep. ad Cled., 1., observe that in saying this we are not looking to the question of soul and body. For when we compare together the soul and the body it cannot be said that they are of one nature. But since there are very many subsistences of men, and yet all have the same kind of nature τὸν αὐτὸν ἐπιδέχονται λόγον τῆς φύσεως; perhaps—all admit the same account of the nature,—all can be dealt with in the same way in respect of nature.: for all are composed of soul and body, and all have part in the nature of the soul, and possess the essence of the body, and the common form: we speak of the one nature of these very many and different subsistences; while each subsistence, to wit, has two natures, and fulfils itself in two natures, namely, soul and body.
