Abstract
The double homoousia, confessed by the Council of Chalcedon, is certainly one of the most difficult concepts transmitted by the dogmatic tradition. What can be signified by the affirmation that Christ is homoouion to us, and to each of us? Is it possible to shift a trinitarian understanding, classical since Nicaea, into anthropological meaning in an univocal way, without reason’s injury? If it is the case, we must give the second homoousia an intelligibility right at the intersection of theology and economy, which geometric center is He 5:8 so that Christology can not be understood from the two natures, purportedly known, even metaphysically (God and man), as if it should be enough to understand the mode of conjunction in Christ. This can be done uniquely in an hypostatic way, following the double definition. The hypothesis of the univocity of Chalcedonian faith offers a significance to divinization by clearing its proper location, if, and only if, we engage a new definition of (human) hypostasis, considering that this hypostasis is the one of the Word in that “perfect” man called Jesus.
