The Anathemas of the Second Council of Constantinople, Number 1.

This council took place in 553 AD. The Definition of Chalcedon had perhaps not gone far enough in it's defining of the nature of the union of God and man in Jesus Christ, and some confusion arose. This council confirmed the Definition of Chalcedon, but stressed in particular that Jesus Christ is not just God the Son in a human body, but that Jesus Christ is God the Son. The document produced by this council is a list of 11 anathemas.*

Here's anathema number 1:

I. If anyone does not confess that the Father and the Son and the Holy Spirit are one nature or essence, one power or authority, worshipped as a trinity of the same essence, one deity in three hypostases** or persons, let him be anathema. For there is one God and Father, of whom are all things, and one Lord Jesus Christ, through whom are all things, and one Holy Spirit, in whom are all things.

*An anathema is a strong denunciation of someone, or a declaration that they are heretical.

**Hypostases means persons.
