Oliver Cromwell was not acting at the behest of the leader of his church (for Protestants, that Jesus), unlike the Catholic Crusaders, who served at the behest of the leader of their church, Innocent III, who supposedly served in place of Christ(Vicarius Christi).
Cromwell was acting on the disturbed ideas of Luther. Luther was the leader of the Protetant hog wash. This makes Luther the head of your church. Ergo, Cromwell was acting on your leader’s initiatives.
What makes it worse is that Cromwell pointlessly slaughtered for his own blood lust. He killed the innocent and unarmed. He killed anything that was Catholic. Then he usurped all power during his reign and brought people down to a whole new level of coarseness.
The Crusaders on the other hand, fought the Muslim armed invasion that reached as far north as Vienna. And the Muslims were close to taking it. They were a very powerful and organized army.
What stopped the Muslims was a series of freak rainstorms. An Act of God in favor of the Crusaders.
The Crusders also gave thier life with no expectation of any earthly rewards. They acted out of piety and humility.
You should be thankful for what the Crusaders did. Otherwise you would be praying to Allah now and we would not be having this discussion.
And Innocent III was the Vicar of Christ as are all Popes. It was decreeed by God and handed on through Jesus.
Remember, Jesus was a priest of the Order of Melchizedek. Jesus ordained Peter as the first Pope. And the rest have found thier origin through Apostolic succession.
You really shouldn’t be so hostile. It makes you come cross as a Cromwellian.
Get over your hate already and become Catholic.
