184. You can clearly tell that a trinity of gods dwells in the minds of Christians - although out of shame they would never say so - by the way many of them ingeniously demonstrate that three are one and one is three. They use various phenomena in plane geometry, solid geometry, arithmetic, and physics, as well as folding pieces of clothing and pieces of paper. Like a bunch of clowns, they horse around with the divine Trinity.
Their clowning is like people's eyesight when they have a fever: they see one object, be it a person, a table, or a candle, as three objects, or three objects as one. It is like the trick people play by softening wax in their fingers and pressing it into different shapes. First they make a three-sided shape to show the trinity; then they make a ball to show the unity, and they say, "Isn't the substance one and the same?"
Truly, though, the divine Trinity is like the pearl of great price [Matthew 13:46]. Dividing the Trinity into persons is like cutting a pearl into three parts: it completely destroys the pearl.
