- "May the Father of Understanding guide us."
- ―A Templar blessing.[src]
The Father of Understanding is a subject often mentioned in reverence by Templars, particularly during ritual ceremonies or as a form of greeting.
While it is not well established whether or not it refers to a literal entity, such as a deity, it is meant to allude to the principle of order that the Templars embrace. What it symbolizes is more important to them than what it is, personifying the logic they appeal to in their dream to shepherd the world.
In the Third Crusade, the Templars would usually sign his name before theirs in letters they wrote. During the Renaissance, Templars would often ask him for guidance as a greeting, or at the end of a meeting.
Before and during the American Revolutionary War, the phrase was used twice by Haytham Kenway; first during the induction of Charles Lee to the Templar Order, and secondly when Haytham was required to enter the Smith and Company Brewery with his son, Connor.
During his investigation into the Templars' affiliation with the Cult of Baphomet, Arno Dorian required a password to gain entrance into the cultist's lair. He was informed by another Assassin that the password was "The Father of Understanding".
