Sorry Aspen, but this is not true. You will, however, find some things that the early church and the Catholic church are in agreement in. The same is also true for JW's, Mormons, Arians, etc... Having some agreement does not validate our beliefs. Everyone can claim some level of orthodoxy. The Roman Catholics have many truths that were founded in the 1st to 3rd centuries. If this was not the case, I suppose that no one would be Roman Catholic. I personally believe they were ordained as an institution, as we spoke of at an earlier time. That does not mean that an ordained institution has God's absolute approval. The seven churches that are mentioned in Revelation are all ordained institutions by God. They are clearly not all approved by God, as most are called to repentance for their terrible sins. The Roman Catholics and the Protestants both fall into this category. Although they have been ordained, they still need to repent of their gross sins.
This is why the book of revelation was written to the seven churches (Rev 1:4). The future (revelation) church is the seven churches (Rev 2 & 3). This is why Paul wrote to seven different cities (Romans, Corinthians, Galatians, Ephesians, Philippians, Colossians, and Thessalonians). The seven cities are the seven churches. This is why there are seven epistles bearing individuals names (Timothy, Titus, Philemon, James, Peter, John and Jude). The individuals are the seven churches. The church, the entire church, is pictured as seven; just as the entire Israel was pictured as twelve. The entire church, including Roman Catholics, believe in (some) false doctrines (Nicolaitans); they follow (some) false prophecies (Jezebel); there are some who are worldly (Balaam), there are some who store up their wealth (synagogue of Satan), there are some who submit to government propaganda (Balak), etc. From these things every church is called to repent.
The book of revelation is a message to the entire church on our need for repentance at the time of Christ’s arrival, and what will happen to us if we do not repent. All of us want to think that our church is ordained; and it is! All of us want to think our church is pure; it certainly is not! The revelation was written so that we would see things from God’s eyes, only then can we have “eyes that see”.
God Bless
