Mr G, in all fairness you are asking 'unanswerable' questions. They are unanswerable for the following reasons:
1. Sicso's answer, Salza's answer, your answer, my answer - they mean nothing - we aren't the Church. So, who cares what their answer is?
2. You are trying, by simple logic, to form a conclusion of heresy and loss of office based on facts + canon law. But the Church doesn't work that way, in regards to heresy. The Church is a monarchy, not a democracy. "We the people" cannot make decisions, only the Church can. Until She does, we wait.
3. You want 'yes/no' answers to very complex questions - ones that are so complex that theologians have been arguing about them for centuries. They are not 'dodging' your questions (which are valid and important) just pointing out that the questions are not as simple as you would like them to be.
