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.

104. A similar thing would happen to us if we were to embrace the faith of the new church but also hold onto the faith of the former church regarding the assignment of the Lord’s justice or merit, since from the latter concept as from a root all the tenets of the former church have risen up like shoots.

If this were to happen, it would be like people escaping from three of the dragon’s heads but entangling themselves in the other four. It would be like running away from a leopard but stumbling onto a lion. It would be like climbing out of a dry pit only to fall into a water-filled pit and drown.

(The truth of this statement will be further shown after the discussion of the next proposition [§§109– 113], where the topic of being assigned spiritual credit or blame is taken up.)
