“#3 Anothers presence in heaven has no bearing on anothers in heaven.”
Almost right but don’t forget there is one exception. Jesus’ presence in heaven definitely has bearing, as he opened the way for the rest of us.
The context was another human. A sinner. If Mary is alive in Heaven now or not has no bearing on ZBs status was the point. But it does give credence to the fact that the Mary Cult is out of their jurisdiction in regards to what Scripture tells us.
