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.

458. These points clarify where the connection between loving God and loving our neighbor comes from and what it is like: God's love for people flows into us; when we receive that love and cooperate with it, it becomes love for our neighbor.

Briefly put, the connection accords with the following saying of the Lord's:

On that day you will recognize that I am in my Father and you are in me and I am in you. (John 14:20)

And this saying:

The people who love me are those who have my commandments and do them. I will love these people, manifest myself to them, and make a home with them. (John 14:21-23)

All the Lord's commandments relate to loving our neighbor. In summary form, they involve not doing evil to our neighbors, and instead doing them good. According to the Lord's words just quoted, people like this love God and God loves them.

Because love for God and love for our neighbor are connected in this way, John says:

Those who keep the commandments of Jesus Christ live in him, and he lives in them. If any say, "I love God in every way" but hate their brothers and sisters, they are liars. If they do not love their brothers and sisters, whom they see, how can they love God whom they do not see? This commandment we have from him: that people who love God also love their brothers and sisters. (1 John 3:24; 4:20-21)
