Thus Spat the Nazarene
In Dungeons & Dragons, spells have verbal, somatic (gestural) and material components. When Jesus cast spells, he used all three, as evidenced in Mark 7:33–34, when he heals a deaf man with a speech impediment:
“And he took him aside from the multitude, and put his fingers into his ears, and he spit, and touched his tongue; And looking up to heaven, he sighed, and saith unto him, Ephphatha, that is, Be opened.”
A similar event is recorded in John 9:6–7, when he heals a blind man:
“When he had thus spoken, he spat on the ground, and made clay of the spittle, and he anointed the eyes of the blind man with the clay, And said unto him, Go, wash in the pool of Siloam . . . ”
Bible Ask notes that spittle had healing properties according to Jewish tradition and Greco-Roman beliefs, before going on to explore possible spiritual significances. I just like it that Jesus keeps his clerical spells (okay, miracles) simple: spit and mud, a touch, a few words.
