I suppose my point is that Christ is united to His Church. She is the instrument through which He continues to spread His saving Gospel to the world. As per His promise to the Apostles to remain with Her to the end of time, and as per His promise to send the Holy Spirit to Her, She alone can authoritatively speak in His Name ("He who hears you, hears me") - the Name above all other names. Whatever conclusions I, or you, come up with individually are meaningless if they are separated and/or contradict His teachings through His Church. My existence as a Christian has no meaning except as being united to Christ's Church.
Hence the authority of the Holy Scriptures is known to be the Word of God, but only through His Church. Once we know which Books are in the Bible (and even here, there are slight differences between Catholics and some Protestants), who has the authority to correctly interpret them? Therein lies the problem.
I suppose that this is what the ministers in the posted article have discovered. Their whole view of the Church, which St. Paul calls the "Pillar and ground of Truth", has changed to the point that they recognize it as being more than merely groupings of people in different localities.
Our Lord meant for all His followers to be united in One Faith, One Baptism, One Church - because He is One. He did not establish "denominations". Hopefully, one day this will be realized.
