38. I would like to add to this a few sentences from the Belgic Confession, which was officially adopted at the Synod of Dort:

I believe in one God, who is one single essence, in whom there are three persons, really, truly, and eternally distinct according to their incommunicable properties — namely, Father, Son, and Holy Spirit. The Father is the cause, origin, and source of all things, visible as well as invisible. The Son is the Word, the wisdom, and the image of the Father. The Holy Spirit is the eternal power and might, proceeding from the Father and the Son. But it must be said that this teaching far surpasses human understanding; we are waiting to know it fully in heaven. (Belgic Confession [8, 9])

64. 15 The faith of the modern-day church has given birth to horrifying offspring in the past, and is producing more such offspring now: for example, the notion that there is instantaneous salvation as a result of the direct intervention of mercy; that there is predestination; that God cares only for our faith and pays no attention to our actions; that there is no bond that unites goodwill and faith; that as we undergo conversion we are like a log of wood; and many more teachings of the kind. Another problem has been the adoption of [false] principles of reason that are based on the teaching that we are justified by our faith alone and the teaching concerning the person of Christ, and the use of these principles to judge the uses and benefits of the sacraments (baptism and the Holy Supper). From the earliest centuries of Christianity until now, heresies have been leaping forth from a single source: the body of teaching based on the idea that there are three gods.
