The Catholic Church never claimed to be the true church of the Bible. The Catholic Church IS the church established by Jesus Christ. Why would anyone leave the Church Jesus personally established?
Actually you're wrong here. the Church in scripture is always referred to as "The Church of God"....eleven times. It is referred to as The Church of Christ once.....never being referred to as "The Catholic or universal Church".
Jesus himself [John 17:11] prays that God The Father will keep the Church in His (God's) own name. He was never called Mr. Universal. The Church of God has been in existence from the Day of Pentecost. The Catholic Church came along much, much later.
Can't be...Your church has some unsaved sinners in it...Jesus' church has NO unsaved sinners in it...Would be an impossiblility for an unsaved person to be a member of the church Jesus founded...Therefore, you got the wrong church...
