Opus Dei is an extreme reactionary group within the church. Leo XIII was a liberal pope responsible for the social doctrine of the church (this text).

Personal experience: when I was in high school in my country there was a teacher who was in Opus Dei. He tried to recruit students by leaving them a letter and inviting them to a "scholarship". I got such a letter, I was so excited. The school found out about that and investigated. We're a mixed-race country. The Opus Dei teacher has invited exclusively white students. He had invited top students #2 to #4 in my class by grade, but not #1, who was black.

Meanwhile I mostly interacted with Opus Dei members near Harvard that were Nigerian, Spanish, and Mexican.

Each country has their own racial hierarchy that may not, and usually does not, match yours.

This was the US.

Where they wealthy? That's the only thing the Opus Dei cares about.

> We're a mixed-race country

There are single-race countries?

Depending on how you count, Egypt, Morocco, Bangladesh, North Korea...

i know what you mean, although they're not single-race (i hate using this expression, omg) in a binary way. or at least only if you exclude the minorities in these countries who still make it diverse, be it in a small way.

When I visited an Opus Dei house once for a philosophy lecture they were discussing Plato, the Timaeus in particular.
