Catechesis: Person of Christ

We believe, teach, and confess that there are now in this one, inseparable person of Christ two distinct natures, the divine, from eternity, and the human, which was assumed into the unity of the person of God’s Son in time. These two nature can nevermore be separated nor mixed together with each other, nor can one be transformed into the other. Rather, each remains in its own nature and essence within the Person of Christ for all eternity.—FC SD VIII:7
