I didn’t read if the Episcopal ‘priest’ did anything during the Mass or just sat there as I have done.

It's a bit later in the article, down below the excerpt. Here's the relevant passage:

[Rev. Annette Chappell, the pastor of the Episcopal Church of the Redemption in Locust Point] did not participate in the consecration of the Eucharist but read the Gospel at the service, Martin said. Someone at the service reported to the archdiocese that Martin gestured to Chappell to take Communion, though Martin said he did not recall doing so.

Only ordained priests and deacons may read the Gospel at Mass, and non-Catholics may not receive Communion.

I thought the article meant that she attempted to concelebrate (assist at the consecration of the Eucharist).

This is a fairly stiff penalty for letting her read the Gospel, IMO, but that was obviously only the latest in a series of issues.

Good to see a bishop with backbone. It will be interesting to see what he does with, e.g., Barbara Mikulski.

I think you are right about those who can read the gospel during the Mass, but Catholics allow members of the Orthodox, Assyrian Church of the East, and Polish National Catholic Churches to receive Communion, although it is urged that members of those Churches respect the discipline of their particular faith. To my understanding the Orthodox do not allow their members to take Catholic Communion, and I’m not sure about the other two Churches.
