"That saying of John has no relevance to the status of Mary. Why are you using it?"
If Mary was a saint who died and went to heaven, then Johns descriptions of the saints in heaven would have been a description of Mary.
Johns descriptions of the saints in heaven is not one of saints who can make intersession, but of saints waiting for the final judgment.
If you believe what John wrote were
just the sayings of John, then I can't help you.
