Important and excellent points - thank you.  It is why I wondered if +Burke could be removed from the cardinalate.  I know there are precedents for doing so, but I don't know if it a practice of the Church in the past one or perhaps two centuries, other then errant cardinals being removed from their positions while retaining the title, etc.  In any event, there is no prohibition for Pope Francis to start a new option in Church discipline with Burke, and his three cohorts who so inappropriately challenged the pope over AL.  I pray that Burke is stripped of his privileges as cardinal well before the next conclave.
