I enjoy reading your post.

Did you go to a Sunday Mass in St Peter’s Square?

When you see
tens of thousands of believers;
standing room only in St Peter’s Square;
people from all over the earth;
believers from Israel sharing a sign of Christ peace with brothers/ sisters from Palestine,
you know what it means to be catholic.

It’s kind of like heaven. Saints from the whole human History rejoice together.

In Catholic Theology, Heaven and Earth unite during Holy Mass (some pictures in your post show this Theology).
