Did the Medieval Papacy seemingly have full temporal authority over most Christian Nations,two examples being ,Pope Adrian Donation Of Ireland to Henry King Of England,and two Pope’s commanding Scotland to submit to English rule,when the Papacy had only temporal power over Vatican States.
The 2nd and 3rd excommunications of King Robert Bruce of Scotland ,and interdict of Clergy and Nation for not submitting to England at the Pope’s command,were political not religious authority
So how could the Pope excommunicate on temporal authority on political matters? (Render to Caesar the things that are Caesar’s) when his function is in religious matters,so excommunications fully valid.
So the Scots Nation were fully justified in disobeying the Popes commands which were political
Even the Church says that some Medieval Popes were involved to much into politics,rather than religion.
The Vatican were against USA and UK,invading Iraq illegally,but this was also a political announcement so no excommunication could be pronounced on Catholics for being in the invading forces
