Saints - H

Hagiography = This is the branch of academics that covers the Saints, their lives and their literary works. It is essential to the nature of the Priests as a Petitioner Order and so every Priest will have at least a minimum level of knowledge in Hagiography. For more info see Hagiography. 
Halo = The Halo is associated with holiness and is often gifted to members of the Order of Priests who prove their faith in the forces of Light. For more info see Halo.
"Holding God Hostage" = This is a common charge against the Priestly Order: they won't let anyone speak of God if they feel it goes against their scripture (or interpretation of scripture). Like Fundamentalists, they label anything that doesn't fit with their very specific idea of God as heretical and 'anti-Christian,' and they tend to flame war anyone online who tries to have a conversation about their own ideas of God. This has led to some of the Priests detractors labelling them 'God's Troll Army.' 
Holy Mace = The Holy Mace is a division within the Order of Priest that trains it members to be warrior priests who serve God and the saints out on the battlefield.
