I've read that pgyanke. It starts off with #781 which has part of it's belief that the "church" has superseded the nation of Israel. It has not. The nation of Israel is once again being gathered by God just as He promised He would do. The nation of Israel still has seven years of the 490 years promised to it. The ekklesia of Christ is separate from the nation of Israel.
Also, the rest of page you sent me to presumes that the Catholic Church is the "church" referred to in scripture. It can not be that "church". The Catholic Church includes beliefs not taught by the apostles and incorporated pagan beliefs and practices. There is no way the Catholic Church can be that "church" spoken of in scripture.
So says you. However, Christ has been building His Church (as He promised He would) for 2000 years. She has been enriched by the intellects and faith of great saints, clergy, laymen and doctors. She has withstood challenges far greater than those posted on this forum and endeavored to keep teaching all who would listen. You are not the first to think they have "gotcha" arguments for why the Church can't be the Church and you will not be the last. History reads like this forum with challenge and response. Those who can not accept go their way as disciples did in John 6 because the teachings are hard and mysterious. We simply walk by faith and not by sight following what Christ has built and continues to guide.
God bless.
