Freemasonry isn’t and has never been a religious organization. It has always been open to members of all religions and faiths. However, the world into which it was born, in Enlightenment-era Europe, was a largely Christian one. As a result, many of the symbols of Freemasonry reflect Christian iconography—including the connection to the two Saint Johns in Freemasonry.
Their feast days are closely associated with the summer and winter solstice – underscoring the symbolic duality of the two figures.
