St. Gregory of Neocaesarea
"If you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move." - Jesus to the Apostles, Matthew 17:20.
St. Gregory of Neocaesarea (also called St. Gregory the Wonder-Worker or St. Gregory Thaumaturgus) took this passage very literally. Through his prayers, and entire mountain was moved to make way for a church to be built!
