71. Beloved brethren, we must not deny that there is one substance of the Father and the Son, but we must not declare it without giving our reasons. The one substance must be derived from the true character of the begotten nature, not from any division, any confusion of Persons, any sharing of an anterior substance. It may be right to assert the one substance, it may be right to keep silence about it. You believe in the birth and you believe in the likeness. Why should the word cause mutual suspicions, when we view the fact in the same way? Let us believe and say that there is one substance, but in virtue of the true character of the nature and not to imply a blasphemous unity of Persons. Let the oneness be due to the fact that there are similar Persons and not a solitary Person.
71. Et pie dici potest, et pie taceri.---Non est, 0527B Fratres charissimi, una Patris et Filii neganda substantia: sed nec irrationabiliter praedicanda. Sit una substantia ex naturae genitae proprietate; non sit aut ex portione, aut ex unione, aut ex communione. Potest una substantia pie dici, et pie taceri. Habes nativitatem, habes similitudinem. Quid verbi calumniam suspiciose tenemus, rei intelligentia non dissidentes? Credamus, et dicamus esse unam substantiam; sed per naturae proprietatem, non ad significationem impiae unionis. Una sit ex similitudine, non ex solitudine.
