Does relationship make real distinction?

CCC says " the term “relation” to designate the fact that their distinction lies in the relationship of each to the others."(P252)

Does relationship make real distinction? How can we prove it?

You don’t “prove” mysteries - they’re mysteries!

If you want something more philosophicallly technical than the Catechism, you might try St. Thomas Aquinas on the divine relations in the Holy Trinity.

Well, sure you do. You prove that the mystery is real, even if you can’t explain why it’s real.

The Church uses the word “mystery” to describe a truth that cannot be known (with certainty) by reason alone.

Oddly enough, there are no “mysteries” (things unknown by our own senses) within Catholicism. EVERY “mystery” of the Church is something that we KNOW ABOUT, but could not know about unless it was revealed by God.

There are UNKNOWNS within Catholicism (such as the fate of unbaptized dead infants, and the criteria of invincible ignorance), but these are not termed “mysteries.” In Catholic parlance, anything that is a “mystery” is something we KNOW about.

It does in God. Just think of the relationship between a Father, a Mother, and a child in a family. Their relationship indicates a distinction in Persons. We can’t expect to understand and should not attempt to understand how this relationship exists in God. It is a Mystery and only God can explain it. But look at Christ’s life. We see Him, yet he is still united with the Father and the Holy spirit. And at Christ’s baptism we saw each of the Persons present in separate forms for our benefit. Yet, in reality, each was actually united with the other. But we cannot see that, only God can see and experience their ontological union.
