The Sovereign Military Order of Malta is so exclusive that passports are only granted to the three highest-ranking officers in the Catholic order, The Sun reports.
The chosen few in possession of the prized red book are the grandmaster, deputy grandmaster, and chancellor of the Order.
The group’s sovereignty is also expressed on licence plates, stamps and coins.
The Order was officially recognised by Pope Paschal in 1113AD and is one of the oldest institutions in the Christian world.
It currently operates as a charitable organisation, offering medical aid around the globe, and doesn’t control any territory of its own, despite having diplomatic relations with more than 100 states.
There are more than 13,500 knights, dames and chaplains in the Order, along with 80,000 volunteers and 25,000 medical employees.
Germany currently enjoys the most powerful passport in the world, which allows its citizens to travel to 176 countries out of 218 without a visa.
