I hope that Joanna's reporting is true but a serious difficulty arises here: would the mother of the Catholic Church want conversions to the partly
heretical,
schismatic Orthodox Church, which does not acknowledge the supreme authority of the Pope?
The detail of the argument was not - at issue — it was enough that Luther was challenging authority, Popes and Councils alike, and defending Huss, a heretic known in the popular mind as one who said the laity should receive the wine at communion (not in fact an
heretical claim), and whose followers had set up the still flourishing
schismatic Church in Bohemia.
