But The Child That's Born on the Sabbath Day
Percy Weasley – Sunday, 22 August 1976

Wizards don't worship Muggle gods. Walking on water is accomplished with a charm. Potions cure illness. Short of raising the dead, there is little any Muggle god has done that a wizard cannot replicate. Even the Muggle-borns, after a while, seem to lose their faith.

Wizards don't worship Muggle gods, so they don't pray, either. Most purebloods wouldn't even know the meaning of the word.

Yet when Aberforth's message arrives, Percy finds himself with his eyes closed and head bowed, begging for answers and guidance from someone, anyone.

It's a full eight minutes before he Apparates to the Hog's Head.
