37. The concept of a trinity of gods also goes against enlightened reason, as many arguments are capable of establishing. What person of sound reason would be open to hearing that three gods created the world? Or that creating and preserving, redeeming and saving, and reforming and regenerating are tasks undertaken by three gods, not one God? On the other hand, what person of sound reason would not be open to hearing that the same God who created us also redeems, regenerates, and saves us? Since the latter thoughts are reasonable, but the former are not, every group of religious and reasonable people on the face of this earth acknowledges that there is one God.

As we all know, Muslims and some of the peoples in Asia and Africa detest Christianity because they believe it entails the worship of three gods. When Christians are rebuked on this account, they have only one response: that the three persons share one essence, and therefore constitute one God.

I can attest that the reasoning power granted me allows me to see that no world, no angelic heaven, no church, and nothing within any of them could have come into existence or could continue to exist if there were not one God.

8. Faith comes to us through hearing, when we believe that the teachings divinely revealed to us are true and when we trust in God’s promises. Faith is the beginning of human salvation, and the foundation and root of all justification. Without faith, it is impossible to please God and to come into the company of his children. Our justification takes place through faith, hope, and goodwill. Unless hope and goodwill are added to faith, it is dead rather than living and does not unite us to Christ.

We need to cooperate in this process. We have the power to move either closer to or farther away from [Christ]; if we did not, nothing could be granted to us, because we would be like a lifeless body.

Our openness to being justified renews us; this renewal takes place as Christ’s merit is applied to us, as the result of our own cooperation. Therefore we get credit for the works that we do; yet because they are done as a result of grace and through the Holy Spirit, and because Christ alone has earned merit, the rewards God gives us are his own gifts within us. Therefore none of us can attribute anything of merit to ourselves.
