The Belgic Confession · Article 11
The Holy Ghost Is True and Eternal God
We believe and confess also that the Holy Ghost from eternity proceeds from the Father and Son; and therefore is neither made, created, nor begotten, but only proceedeth from both; who in order is the third person of the Holy Trinity; of one and the same essence, majesty, and glory with the Father and the Son; and therefore is the true and eternal God, as the Holy Scripture teaches us.
