Fishinfamily,
Very good question! What would that look like? I am guessing it would continue to be a mess because man is involved. We would continue to argue over infant vs. adult baptism, are the elements of communion symbolic or the actual body and blood of Christ, can souls be symbolically baptized after death, is there purgatory, can the individual read and understand the Bible, is the Holy Spirit a separate person, and on and on… And please do not read that as a Catholic vs Protestant conflict - those issues above span many denominations. You would also have the pseudo-christain cults slipping in muddying up the waters with false teachings.
On the glorious day of Christ’s triumphant return, HE will unify HIS body of believers. Jesus will connect all of the dots and make a beautiful and concise picture of the truth that we cannot see today. There is nothing we can do on our own except accepting Jesus as our Savior and the only one who can make sense of our chaotic and sinful lives and calm our fears of what we do not understand. For me, I have trouble with the word “church” and tend to use “body of believers.” The word “church” has taken on a meaning, for me, that illustrates what we have defined it to be.
