Well, not only women priests were present. And the rest of us was not excommunicated. As Catholics we had the very right to attend the mass. We didn't intend to make a disruption; we demonstrated before and with some distance to the Vatican (it's a solid 7-8 minutes walk).  Every Catholic has the right and even the obligation to make their opinions known if they think the Church authorities do something wrong. And so we did. But the Eucharist is holy for us, these were us who were disturbed!
