THE FORTH ECUMENICAL
Held in Chalcedon, near Constantinople, 451. Under
Emperor Marcian. 630 Bishops were present.
The Council was concerned, once again, with the nature of Jesus Christ.
The teaching arose that Christ's human nature (less perfect) dissolved
itself in His divine nature (more perfect): like a cube of sugar in a
post of water. Thus, in reality, Christ had only one nature, the Divine.
Hence, the term: Monophysites ("mono", one and
"physis", "nature".) Monophysitism overemphasized
the divine nature of Christ, at the expense of the human.
The Council condemned Monophysitism and proclaimed that Christ has two
complete natures: the divine and the human, as defined by previous
Councils. These two natures function without confusion, are not divided
nor separate (against Nestorius), and at no time did they undergo any
change (against Eutyches: Monophysites).
