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.

108. The first reason why Roman Catholics are better equipped than Protestants to become part of the New Jerusalem (that is, the new church) is this: The belief that we are justified by being assigned Christ’s merit, which is wrong and cannot live alongside the faith of the new church (see §§102– 104), has been wiped out among Roman Catholics, and should be completely eradicated. This belief is firmly fixed in Protestants, however, as if it were carved into their being. It is the chief teaching in their church.

The second reason is that Roman Catholics have more of an idea than Protestants that there is divine majesty in the Lord’s human manifestation. This is abundantly clear in the extremely sacred way in which Roman Catholics venerate the Host.

The third reason is that Roman Catholics see goodwill, good works, repentance, and the effort to live a new life as essential to salvation; the new church, too, considers them essential. Protestants who are committed to faith alone, though, have a very different view. They see these as playing a nonessential role or even no role at all in our faith; they see them as contributing nothing to our salvation.

These are three reasons why Roman Catholics, if they turn to God the Savior himself directly rather than indirectly and if they take both elements in the Holy Eucharist, are better equipped than Protestants to receive a living faith in place of a dead one and be led by the Lord, through the agency of his angels, to the gates of the New Jerusalem (the new church) and brought in shouting for joy.
