Remember that unlike GURPS, the Dungeon Fantasy Roleplaying Game has very limited social traits and roles!

The nominal social trait of clerics is Clerical Investment, which is about blessing holy water (that's why it's cheaper), leading prayer, sanctifying altars, and trading favorably in holy relics. In short, it's about sacraments.

The nominal social trait of holy warriors is Born War-Leader, which is about military command. It comes alongside Rest in Pieces and a Higher Purpose for killing monsters. In short, it's about destroying enemies of the faith.

Clerics are celebrants and seminarians. Holy warriors are crusaders and temple guardians – knights loyal to a god (or mortal cult leader) rather than to a land (or mortal sovereign). They've taken completely different holy orders to the same church.
