The Templars and many similar organizations were mostly christian but had occult circles in which many high ranking members were occult satanists.
An interesting point of view, but I believe that the Templars were not a christian organization and all the monarchs of that time knew this very well, of course they could tell the peasants something else (allegedly profess christianity), but no one took into account the opinion of the peasants.
If you look at the structures of many chivalric orders and their symbols of that time, even crosses, then as a rule there is nothing christian about them.
The crosses depicted on the symbols of the Templar Order and the Teutonic Order (as well as many others knightly orders, of course not all knightly orders) are pagan symbols that are depicted on many sigils of Demons.
If you look at the rituals of the Teutonic Order, which HPS Pythia referred to in old sermons, then are purely pagan rituals.
In the European kingdoms, too, everything was not so clear.
If we take the European kingdoms, for example, the Slavic kingdoms (Grand Duchy of Lithuania), then up to the reign of King Jagiello, the Grand Dukes of Lithuania adhered to paganism, for example, King Mindovg.
According to the Gustyn Chronicle, in 1246 in Novogrudok he converted to orthodox christianity, guided exclusively by political considerations, which were based on his desire to rule in the Old Russian Novogrudok.
After Mindovg's rival, Lithuanian Prince Tovtivill, who was sitting in Polotsk, arrived in Riga and converted to catholicism there, frightened by the threat posed by the Livonian Order, Mindovg also converted to Catholicism in 1252.
With the weakening of the threat from the Germans, in 1260 he returned to paganism, which he had never actually left, from the moment he returned to paganism, he entered into a serious conflict with the Vatican, but at that moment his kingdom expanded, as the territories where pagans lived voluntarily decided to join him.
