It looks like the Catholic Church.<quoted text>
The Word can be effective and protected through the good and the bad. Some of the most credible witnesses to the fact that there was a Jesus and there was a resurrection were writers of old that tried to discredit it. In their attempt to discredit the Christ God used them to help bring credibility to the facts that cannot be denied, Jesus lived, walked the earth, and has no grave.
I'm not sure if the point I'm trying to make will be understood, but God's Word will survive. History shows that the Word has spread most effectively when Christians are being persecuted for their faith and when all they believe in seems to be lost.
Look at the worship practices and the church government the inspired Apostles implemented and we read about in scripture. Does that look like the Catholic church or the church of Christ?
It's visible and hierarchal, as in scripture, and they believed that Baptism was salvific and that the Eucharist is the body and blood of Christ.
They did this with a uniformity of belief without making reliance on their personal interpretation of Christ's teaching. They also did it in the absence of a Bible.
