This is an important question, especially with respect to the Knights Templars.
In fact, Bl. Pope John Paul II has approved a small religious Order which is based on a reformed Templar rule (it is a Traditionalist Order, FYI).
A reconciliation between the Church and the Templars wouldn’t be out of order. There aren’t any Templar saints, even though, as in the Battle of Hattin, 80 Templars were beheaded, one by one, as they were forced to approach a Cross that was set up by the Saracens and told to spit on it. They all refused. They are true Martyrs . . .
There was no reason for the violent deaths of Jacques de Molay and Geoffroi de Chancey and other Templars killed by the French Inquisition. A sad page in the history of the Church.
So much nonsense has been written about the Templars, movies and the like, as well as “Templar Orders” that have nothing to do with their original purpose and are even pagan in outlook.
It would be great if the Church could revisit the trial of the Templars with the view to exonerating those murdered/martyred (much like what happened with St Joan of Arc).
There are many Templars, martyred for the Catholic Faith, who deserve the honours of the altar as well.
