21. 3 The leading reformers — Luther, Melanchthon, and Calvin — retained all the dogmas regarding the trinity of persons in the Divine, original sin, the assigning of Christ’s merit to us, and our being justified by faith, in the same past and present form they had had among Roman Catholics. The reformers separated goodwill or good works from that faith, however, and declared that our good works contribute nothing to our salvation, for the purpose of clearly differentiating themselves from Roman Catholics with regard to the essentials of the church, which are faith and goodwill.

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.
