17. 1 The churches that separated from Roman Catholicism during the Reformation disagree with each other on many points of theology, but there are four points on which they all agree: there is a trinity of persons in the Divine; original sin came from Adam; Christ’s merit is assigned to us; and we are justified by faith alone.

97. It is very different with the tenets or teachings of the new church, though. All of them are essential elements. Heaven and the church are present in each one of them. The goal toward which they aim is for us to be in the Lord and for the Lord to be in us, according to his own words in John 14:20; 15:4, 5, 6. Simply put, the [true] Christian church is this type of partnership with the Lord.

From the mere handful of points just made, we can clearly see the meaning of the Lord’s words:

The one who sat on the throne said, “Behold, I am making all things new”; and said to me, “Write, because these words are true and faithful.” (Revelation 21:5)
