This is the fatal weakness of every such meeting and overture. Other Christians approach things with the idea they are equals with a goal of fellowship. The Roman point of view is that the only goal is that the other eventually submit to Rome again.
Until Rome gives up the idea that they are the only legitimate leader of all Christiandom, I cannot see that meetings will ever produce much success.
Rome is like a guy trying to get an old girlfriend back. At best she is open to be a friend, but he thinks she is going to walk back in and say she was wrong to leave him.
I agree with your analysis.
The chances that we will “submit” to the Roman Pope are exactly zero! I doubt, however, that that is what this Pope is looking for. In any event, we CAN work together closely.
