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.

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.
