Summary: In the De Synodis, Hilary of Poitiers tries to attract the Homoiousians to the acceptance of the Nicene formula. For this he explains to them that the Nicene meaning of homoousios is not monarchical as they fear. He adds that transmission by generation does not admit change in the nature transmitted, the son is always of the same nature as his father. And the divine nature has no comparison, so what the Father transmits to the Son can only be his own. Under these conditions, saying homoioúsios is equivalent to saying homooúsios.
Keywords: Nicaea, homoousious, Hilary.
Abstract: In De Synodis, Hilary of Poitiers sought to attract the homoiousians towards accepting the Nicene formula. In order to do so, he explained that the Nicene sense of homoousious was not monarchian, as they feared. In addition, he said that what is passed down through generations does not allow changes in the nature of what is transmitted; the son is always of the same nature as his father. Furthermore, divine nature cannot be compared, and, thus, what is transmitted by the father to the Son can only be his own. In such conditions, homoiousious is equivalent to homoousious.
