Who are you trying to kid? Lefevre was indeed permitted to consecrate a bishop. One bishop. He chose instead to consecrate Four. In absolute disobedience to the Roman Pontiff. After being told explicitly of the consequences of such acts! Yes, JPII had the right to allow Lefevre to consecrate ONE bishop. Only one, if JPII thought that prudent. Your plea to emotionalism and necessity does not change this.
And the Indult was granted prior to this, so no claims such as yours here apply.
Would you admit that there are limits to what even a pope may command legitimately in such a dire situation?
No. Rome has spoken. Rome decided it was not dire. Closed case.
Would you admit the past few decades sheds fresh light on what Lefebvre saw
Yes
clearly as an attack on the faith itself which he properly and in good conscience rejected?
No, when he disobeyed the Pope he acted not out of good faith or good conscience but out of foolish pride, thinking he, a bishop, knew better what was right for the Church than the Pope elected by the Holy Spirit.
