7. It is known that the doctrines of the churches in the Christian world teach that God is one. This they teach because all their doctrines are from the Word, and so far as one God is acknowledged both with the lips and the heart these doctrines are consistent. To those who confess one God with the lips only, but in heart accept three, as is true of many at this day in Christendom, God is nothing but a word on the lips; and all their theology is a mere idol of gold enclosed in a shrine, the key to which the priests alone hold; and when such read the Word they perceive no light in it or from it, not even that God is one. To such the Word appears blurred with blots, and in regard to the unity of God entirely covered with them. It is these who are described by the Lord in Matthew:
In hearing ye shall hear and shall not understand; and seeing ye shall see and not discern. Their eyes they have closed, lest haply they should see with their eyes and hear with their ears and understand with their heart, and should turn themselves and I should heal them (Matt. 13:14, 15). All these are like men shunning the light, and entering chambers without windows, and groping about the walls, searching for food or money, and at length acquiring a vision like that of birds of the night, seeing in darkness. They are like a woman having several husbands, who is not a wife but a lascivious courtesan; or they are like a virgin who accepts rings from several suitors, and after the nuptials bestows her favors not upon one only, but also upon the others.
